Arizer Go SRT Review & Owner's Guide (2026): Tested, 8.6/10

The Hook: The M&S Dine In for Two

Sarah's got a Friday night routine. Sometime around five past six, she walks through the door, puts her bag down, opens the fridge, and goes "shall we do the M&S one?"

The M&S Dine In for Two. Main, side, dessert, bottle of wine, twenty-five quid. It's not fine dining. It's not trying to be. It's the complete package — considered, reliable, grown-up food that makes a Friday evening work without anyone having to think about it. Nobody's writing Michelin reviews about M&S lasagne. But when you want the evening to just happen, without a 45-minute wait for a table and a bill that makes your eyes water? You do the Dine In.

It's not the Mighty+. It's not trying to be the benchmark session vape. It's not the Solo 3 v2, which is what Arizer make when they want to win the flavour Olympics. And it's not the ArGo, which is the sandwich-meal-deal version — smaller, cheaper, still perfectly good for what it is.

The Go SRT is the complete package. Five-to-fifteen-second heat-up. A 21700 battery Arizer can replace. Go Shells for pre-loading. Glass path that seals inside the body when you cap it. Lifetime warranty on the heater, two years on the device, one on the cell. Travel case, water pipe adapter, dosing shells — all in the box.

It's what Arizer make when they stop trying to redefine the genre and just build a proper portable that doesn't make you compromise on anything.

And — I'll get to this — it's the first Arizer portable that didn't require Sarah to hold her handbag open with one hand and pray nothing snapped.

We stock the Go SRT at HerbVape.co.uk — details and pricing below.

Vapour Quality 9/10

Right. Let's talk about why you're here.

The Go SRT runs the 75/25 hybrid heater Arizer have been refining since the Solo 3, now in a body 30% smaller. That's the headline. The convection side handles the extraction, the 25% conduction from the chamber walls keeps things consistent and fast, and the all-borosilicate glass vapour path delivers flavour that still makes S&B owners shift in their seats.

First draw at 185°C on a Gentle-to-Balanced preset: that familiar Arizer glass-path clarity. The terpenes come through sharp, clean, distinctly themselves. Nothing between you and the flower except glass and airflow. I've said this before in the Solo 3 v2 review — the glass path makes a difference you hear, not imagine — and the Go SRT inherits that quality straight from its bigger brother.

The catch: this is a smaller device with a smaller oven. The Go Shells hold about 0.2g, the standard aroma tube slightly less. You're not getting the 0.2–0.25g of the Solo 3's XL pod. What you're getting is focused, efficient extraction across shorter sessions. Draws 1-4 are exceptional. Draw 5 onwards depends on how you've paced the temperature stepping.

The Solo 3 v2 still wins on raw extraction power and bowl longevity — there's just more device there, more airflow, more thermal mass. But nothing else in Arizer's portable range combines this flavour purity with actual pocket-friendly portability. The Go SRT earns that.

Packing Guidance:

• Go Shells: ~0.2g, medium-fine grind, tamp gently. The shells respond well to slightly tighter packs than the classic stem system
• Glass Aroma Tube: 0.15–0.2g, medium grind, loose pack with 2mm headroom
• WPA sessions: Shells work better than tubes for water pipe use — more efficient extraction under the increased draw resistance

Why grind matters so much in a small oven, and the ten-second habit that fixes a thin first draw, are in the owner's guide below.

The Strain Test

Nothing on the shopping list varies between reviews — the jars, the grinder and the running order are fixed, and the device is the only new ingredient. The question for the Go SRT is whether M&S portion sizes cost you anything at the table — smaller plates, but the same kitchen behind them.

Jack Herer — Sativa

The Flower: Same jar as every other device on this site. Haze × (Northern Lights #5 × Shiva Skunk), around 20% THC, terpinolene-led with caryophyllene and pinene behind it. Pale, spindly, hairy stuff that looks less impressive than it smokes — crack the jar and it's pine needles and lemon peel first, dry green herbs underneath, black pepper right at the back. Old-school in the way that means "aromatic", not "weak". It's the strain that shows you up: the top notes are fragile, and if a vaporiser can't hold them you find out in the first three seconds.

The Pack: 0.2g in the glass aroma tube, medium grind, loose with a couple of millimetres of headroom. Tube rather than shell for this one — I wanted the longest, cleanest glass path the device has before anything else got in the way. Stem and shell both went through an ISO soak between strains, as they do in every one of these.

Low Temp (180°C): Draw one and the pine is there, properly there — pine needles and lemon peel, that cooling menthol edge sitting on top. No off-notes, because there's nothing in the path to contribute any: glass, air, flower. Draw two holds it. Draw three is where the small oven starts telling on itself — the lift thins, the citrus goes from lemon peel to a general brightness, and you can feel the heater working rather than cruising.

Mid Temp (190°C): Black pepper arrives on time and arrives clearly, which is the glass doing its job. Underneath it, a dry herbal body and the first of the woody haze. Three draws, denser than the low stage, and by the third the pine is a memory rather than a flavour. Two good draws of top end, then — which is exactly what 0.2g in a small hybrid should give you, and no more.

High Temp (200°C): Earth and toasted herb, a bit of old-school funk on the back of the second draw. Correct, not a failure — this is where Jack goes. ABV came out an even mid-brown with no dark edges, which for a shallow chamber pushed to the top of my stepping is a better result than I expected.

The Verdict: Eight draws, eleven minutes, and the honest summary is that the Go SRT renders Jack accurately for about half the session and then runs out of road. That's the Dine In trade in one sentence: same kitchen as the Solo 3 v2, same glass, same clarity — just a smaller plate, and you notice it when the thing you want most is the first course. Nothing here is muddied or blended; there's simply less of it. If this is your daily strain and you mostly vape at home, buy the bigger brother.

Wedding Cake — Indica-Leaning Hybrid

The Flower: Same jar as every other device on this site. Triangle Kush × Animal Mints, via Triangle Mints #23 — around 24% THC, caryophyllene first, then limonene and myrcene. Dense, squat, greasy nuggets that leave your fingers tacky and your grinder needing a wash. Nose is vanilla and cream over sweet raw dough, with a peppery earth underneath and a cherry-berry edge that turns up on the exhale more than the sniff. Modern dessert genetics doing exactly what it says on the tin. Where Jack exposes a device, this one flatters it.

The Pack: 0.2g in a Go Shell, medium grind, tamped gently — the shells take a slightly firmer pack than the tube without choking, and the tighter airflow suits a heavy profile.

Low Temp (180°C): Vanilla and sweet cream straight off draw one, sweet raw dough behind it, and a cherry edge that turns up on the exhale exactly where it should. Three draws and every one of them is legible — the glass separates the dairy from the dough instead of handing you one sweet blur. A far easier ask than the sativa, and the device knows it.

Mid Temp (190°C): Butter, and then baked cake. Black pepper turns up late in the second draw and stays for the third. Vapour thickens noticeably; the shell's tighter draw concentrates it more than the tube does. The dessert notes still arrive as separate things rather than one warm sweetness, which is the entire argument for a glass path.

High Temp (200°C): Toasted and nutty, caramelised sugar tipping towards a burnt edge on the last draw. Two is the right number here. The dessert has collapsed into general warmth by the end, but it took until the top stage to do it.

The Verdict: Where the sativa ran short, this one fills the plate. Wedding Cake's weight suits a small chamber — 0.2g of dense dessert genetics gives you everything the strain has, and the shell's concentration works for it rather than against it. Are the two strains still obviously two different plants at 200°C? Yes, clearly, which puts the Go SRT on the flavour-device side of the line rather than the delivery-device side. But the fair reading is that the M&S Dine In serves the pudding better than the starter: this is a machine that flatters the robust profile and simply tells the truth about the fragile one.

Design & Build (The Story) 8.5/10

I need to tell you the handbag story.

Sarah's been patient about my Arizer collection. Patient in the way long-suffering partners are patient — with the occasional "why do you have two Solo 2s that look identical?" thrown in for balance. But the one thing she's never gotten on with is Arizer's glass aroma tube system. Those tubes stick out the top of the device. In a jacket pocket, they're fine. In her handbag? One snapped stem in a coat pocket and she was done lending Arizers space in her bag.

Day five, we had dinner booked at a place in Chorlton. Sarah reached for her bag, looked at the three vapes on the kitchen counter, and said "which one am I actually bringing?"

I handed her the Go SRT.

She turned it over in her hand. Found the magnetic On-The-Go Cap. Clicked it into place. The glass stem was gone — sealed inside the body, invisible, protected. She put it in her handbag, next to her phone, and said: "right, this one actually comes with me."

That's the quiet engineering win of the Go SRT. The magnetic silicone cap seals the glass vapour path inside the aluminium body when you're not using it. No more stems sticking out. No more "please don't snap" prayer when you put it in a bag. You pop the cap off, take a draw, cap it again, drop it wherever.

It's the single change that moved the Arizer portable range from "jacket pocket, carefully" to "handbag, without thinking."

The body itself is solid aluminium, 110mm tall, 237g on my scales — Arizer publish neither figure. Matte black, no flex, no rattles. The front panel runs a vertical LED bar display that shows heat-up progress, draw time, residual heat. It's clean and legible without being fussy. Three buttons on the right — ACTION, UP, DOWN — run one-handed operation comfortably even with bigger hands.

The magnetic oven lid and travel cap use the same satisfying click-into-place action. The kind of detail that feels engineered rather than styled.

Materials:

• Body: Anodised aluminium, matte black finish
• Vapour path: All-glass (borosilicate)
• Heater: 75/25 hybrid convection/conduction with stainless steel chamber
• Grips: Food-grade silicone (for handling hot shells)

Battery & Charging (The IT Guy Check) 8.5/10

This is where the Go SRT separates itself from half the premium portable market.

The 21700 cell can be replaced when it degrades — but be clear about how. Arizer's support say battery replacement goes through Arizer, so this is a service job, not a screwdriver on the kitchen table and definitely not a pocket swap with a spare cell at a festival. Don't open it yourself. What it does mean is that a tired cell doesn't have to be the end of the device. Plenty of vapes at this price are finished once the battery goes, which in 18-24 months of daily use effectively makes them landfill. Amit's had three sealed-battery devices die on him across two continents — it's not bad luck, it's physics. Lithium-ion chemistry has limits, and when nobody will replace the cell, the device's lifespan is the battery's lifespan.

The Go SRT has a way out of that: when the cell goes, talk to Arizer (or us), get it replaced, carry on.

Real-world battery life across week one: 10-14 bowls per charge at my standard 185-195°C stepping, depending on whether I'm using shells or the aroma tube. Shells pull slightly more power due to the tighter airflow. Heavy use at 210°C+ drops it to 8-10. Gentle micro-sessions stretch closer to 16. Worth noting: these are new-battery numbers. The degradation story only becomes clear after several months — I'll update properly at the 6-week mark.

Compared to the Solo 3 v2? The Solo 3 pulls ahead on pure battery life (12-15 bowls in a larger body). The Go SRT trades some capacity for portability. Compared to the Crafty+? Different planet. My Crafty+ gasps by bowl four on a good day.

USB-C PD fast charging at 5V/3A cuts recharge from flat to full in about 90 minutes on my bench, against Arizer's quoted one-to-three hours. Pass-through charging is supported — vape while plugged in if you're desk-bound. This is the feature I use more than I expected to, honestly. Working from home, Go SRT plugged into the side of the monitor, topping up between bowls.

The Spec Check:

• USB-C PD: ✓ (5V/3A)
• Fast Charging: ✓ (~90 mins flat-to-full measured; Arizer quotes 1–3 hours)
• Pass-Through: ✓
• Replaceable Battery: ✓ (21700 cell, replaced through Arizer — not a DIY job)

Ease of Use 8/10

The V-Scale preset system is where the Go SRT stops being a dial-and-go Arizer and becomes a smarter device.

Instead of setting a temperature in degrees, you pick from four tiers — Gentle, Balanced, Intense, Extreme — each mapped to a different volatilisation profile. It's not just temperature: it accounts for draw rate, airflow, and session timing. You can also customise the presets on temperature and heat duration.

Once you've spent two or three sessions with it, the logic clicks. Gentle for flavour-first morning sessions. Balanced for the main daily driver. Intense for heavy extraction. Extreme only when you've packed a dense shell and want everything out of it.

Loading is straightforward: pop the magnetic oven lid, drop in a Go Shell or use the glass stem, cap it. Total process maybe twelve seconds. The one operational catch is the Go Shell screen — it's a press-fit metal mesh that sits in the shell bowl, and it doesn't lock into place. Load the shell carelessly and you can dislodge the screen. You get it right by session three. It's a quirk rather than a flaw.

The LED bar display is dim enough to use in the cinema without being a lighthouse. Dark Mode dims it further. Haptic feedback vibrates when you hit temperature. Could Mum use this? Gentle preset, single button press, yes. V-Scale customisation? She'd hand it back. But Gentle preset mode is genuinely simple.

Cleaning & Maintenance (The Gunk Confession) 9/10

Arizer's cleaning story is unchanged, and that's entirely a good thing.

The glass stems and the Go Shells are the only parts that accumulate gunk. The oven itself stays pristine because the herb sits inside the glass or the shell, not directly against the heating element. Resin builds on removable parts that you can soak in ISO. The device itself stays clean.

The Go Shells are technically consumables long-term — the internal metal screens will eventually warp after enough heat cycles, and you'll want to replace them. Arizer sells them in packs. It's a small annual running cost for daily users, considerably cheaper than Mighty+ cooling unit replacements or DaVinci zirconia parts.

Compare this to the Mighty+ CU teardown — eight o-rings, three separate parts, tight corners that trap resin — and you understand why Arizer fans stay loyal. Cleaning the Go SRT takes about forty seconds.

The full routine — daily, weekly and monthly, the deep-clean steps and what never to do — is in the owner's guide cleaning schedule below.

Portability 9/10

This is the Go SRT's actual defining feature. Forget the V-Scale. Forget the Go Shells. This is the first Arizer that fits into daily going-out carry without compromise.

At 110mm × ~32mm and 237g, it's smaller than the Solo 3 v2 in every dimension. Fits in a jacket pocket without printing. Fits in a standard handbag next to a phone without anxiety. Fits in jeans pockets if your jeans have the real estate — not skinny jeans, but proper straight-leg trousers, yes.

The magnetic cap is what unlocks this. Every other Arizer portable has the glass stem exposed when it's in a pocket. The Go SRT doesn't. Cap on, it's a sealed aluminium cylinder. No glass anxiety.

Stealth: the vapour's still visible — it's a hybrid convection vape, not a vape pen — but the device itself is discreet. LED display dims properly for low-light environments. No noise beyond the faint click when you remove the cap. I've used it at the cinema, at gigs, on trains. Nobody's noticed yet.

For genuine stealth situations — like needing something to look like a USB stick — the PAX Plus or XS GO still win. The Go SRT is portable, not invisible. But for "vape that fits in a bag and doesn't announce itself," this is where Arizer's range finally lands.

How I Actually Use This

My Default Setup: Balanced preset (set to 192°C, 4-minute heat time), Go Shells pre-packed the night before, travel case in my jacket pocket. Gentle preset customised to 182°C for morning micro-sessions.

When I Reach For It: Any time I'm leaving the house for more than two hours. Restaurants, the cinema, friends' places, evening walks. The 15-second heat-up means I'm not standing around waiting. The shells mean I'm not grinding flower on someone's coffee table.

When I Don't: When I'm home and want longer sessions with denser clouds, I'll grab the Solo 3 v2 or the Mighty+. The Go SRT's smaller oven means shorter sessions — which is what I want outside the house, not in the living room.

The Honest Carry Reality: I pre-pack four shells on Sunday night. That gets me through three or four outings during the week. When I run out, I either load the glass stem for a single session or reload shells in the kitchen. The prep is part of the routine now.

Session Frequency: Five days across the test week for outside-the-house sessions, plus a couple of at-home uses to compare against the rest of my collection. One week of solid testing so far — the full picture needs the 6-week update.

Medical Use Notes

For Pain Management: The Go SRT's shell-based dosing is genuinely useful for consistent medical use. Pre-load 0.2g shells, know exactly what you're consuming per session. Balanced preset (192°C, 4-minute heat) extracts cannabinoids efficiently without the high-temp harshness. For break-through pain on the go, it's the first portable I trust to deliver consistent dosing outside the house.

For ADHD/Focus: Gentle preset micro-sessions work well. Two or three draws on a 0.15g shell, cap it, carry on with the day. The 15-second heat-up means the device doesn't break the focus cycle, which matters when you're already fighting distraction.

Session Timing: First draw to noticeable effect: 3-5 minutes. The shell-dosed consistency makes titration easier than traditional stem loading.

The Medical User's Concern: The V-Scale preset system has a small learning curve. If you've got cognitive fog or fatigue days, the customisation menus can feel like work. Once your two main presets are dialled in (Gentle and Balanced), it's fire-and-forget.

Value for Money 8/10

For the complete package, the Go SRT is fair money.

You're getting Arizer's refined hybrid heater, the glass vapour path that's defined their brand for a decade, a magnetic sealed-glass-path design that finally makes it pocketable, a 21700 battery Arizer can replace, USB-C PD with pass-through, a lifetime warranty on the heater, two years on the device and one on the cell, and a 14mm water pipe adapter, Go Shells, glass stem, travel case, and grip all in the box.

The competition at this price:

• Mighty+: Costs more. The benchmark session vape — bigger bowl, smoother cooling unit, dedicated home use, not pocketable. Different use case
• Solo 3 v2: Near enough the same money. More raw power, better battery, bigger device. Home-use portable rather than actual pocket portable
• Crafty+: S&B reliability for a bit less, degraded battery anxiety, sealed design, no pass-through. Different trade-off profile
• Air MAX: Similar Arizer experience, older design, 26650 battery system, chunkier. The value alternative

The Go SRT isn't trying to be the cheapest Arizer — that's the Air MAX or the Air SE. It's positioned as the modern premium portable that makes none of the traditional Arizer compromises on pocketability and charging. Over the Air MAX, the extra money buys genuine handbag-carry, faster heat-up, and the shell dosing system.

If you mainly vape at home, the Solo 3 v2 is the better spend. If you mainly vape outside the house and want an Arizer, the Go SRT is the first one that actually earns the "portable" label.

The Verdict (The Bookend)

One week of daily testing. The Go SRT's lived in my jacket pocket for going out, in the travel case for a Chorlton dinner, and on the kitchen counter for morning micro-sessions.

I'll tell you where I've landed so far.

If you want the best Arizer portable for flavour and home sessions, the Solo 3 v2 is still the one. Better battery, bigger oven, more extraction power. If you want the cheapest serious Arizer, the Air MAX is still the one. Same DNA, older design, swappable 26650s.

But if you want the Arizer that actually goes in a handbag without drama, this is the first one that makes it happen. The magnetic cap is the feature that changes everything. Sarah took it to Chorlton on Day five. She's asked for it twice more since. She's never asked for any of my other vapes.

The V-Scale presets took me a week to properly settle into. The Go Shell screens need careful handling. The price is grown-up money. But you're getting the complete package — Shells, WPA, travel case, silicone grip, glass stem, all in the box — and a lifetime heater warranty that Arizer has historically honoured properly.

Sarah does M&S Dine In because she wants the evening to work without thinking about it. Wine, main, side, dessert, done. The Go SRT is that vape. Not the cheapest. Not trying to be. Just the complete grown-up package that makes the whole thing land properly.

What the 6-Week Update Will Cover

Seven days isn't enough time to judge a vaporiser properly. Here's what I'll be testing over the next five weeks, and what could move the provisional 8.6/10 score up or down:

Reliability & QC: Any error codes, heater issues, or haptic/display faults that surface with heavy use. Arizer's recent track record is strong (the Solo 3 v2 sorted the Solo 3 v1's Error 5 problems), but new hardware always has quirks that only emerge past week two.

Go Shell longevity: How quickly the internal screens warp, whether the shells themselves show wear, how often I'm actually replacing screens under daily use.

Magnetic cap wear: Whether the magnet strength holds after hundreds of open-close cycles, and whether the silicone grip starts showing scoring or tears.

Battery degradation indicators: Early signs of bowls-per-charge dropping, charge-time increases, any warmth or voltage-sag issues with the 21700 cell.

V-Scale preset stability: Whether customised presets hold through firmware updates (if any arrive), and whether the system still feels intuitive after the novelty fades.

Real-world portability: Multiple handbag trips, jacket pockets, weekend travel — whether the "passes the handbag test" claim holds across a wider range of situations, not just one Chorlton dinner.

Warranty interaction: Arizer's lifetime heater warranty is meaningful only if the claims process works. If anything goes wrong, I'll document the RMA experience.

Score recalibration: The provisional 8.6 reflects first-week impressions. If the device holds up, it'll likely stay put or move slightly up. If reliability issues emerge, it'll come down — honestly and publicly.

Vs the Competition

The same Arizer DNA in different form factors. The Solo 3 v2 wins on raw battery life, extraction power, and overall flavour ceiling — it's got more device, more thermal mass, more oven. The Go SRT wins on portability, heat-up speed, magnetic sealed glass path, and a 21700 battery Arizer can replace. The two are effectively a quid apart, so price isn't the deciding factor here: if you mostly vape at home, the Solo 3 v2 is the better buy. If you need actual pocket carry, the Go SRT is the only Arizer that delivers it without compromise.

Want the long version? The full head-to-heads: Go SRT vs Solo 3 v2 and Go SRT vs Air MAX.

Price versus refinement. The Air MAX delivers the classic Arizer glass-stem experience with a swappable 26650 cell for a lot less money. It's bigger, chunkier, slower to heat, and the stem sticks out the top. The Go SRT modernises everything: faster heat, a single 21700 cell Arizer can replace, magnetic cap, shell system, USB-C PD. If budget's your primary driver, Air MAX. If portability and modern features matter, Go SRT.

Glass path versus S&B engineering. The Crafty+ gives you S&B's reliability record and extraction style — dense vapour, slightly clinical flavour, a sealed battery that degrades in 18-24 months and no pass-through charging. The Go SRT gives you Arizer's glass purity, a cell Arizer can replace, and pass-through charging. For a bit less money, the Crafty+ is a legitimate alternative if you trust the S&B name and don't mind sealed-battery lifespan limits. The Go SRT is the longer-term investment.

The closest sibling in Arizer's own portable lineup — and the clearest upgrade story. The ArGo pioneered Arizer pocket-carry in 2018 with a pop-top glass stem and swappable 18650; the Go SRT is what happens when that philosophy gets eight years of engineering improvements. Faster heat-up (5-15 seconds vs ~90 seconds), magnetic sealing cap instead of the ArGo's sticky pop-top, a bigger 21700 cell, USB-C PD charging, Shell system for loadout flexibility. The ArGo is a lot cheaper and still disappears into jeans pockets — if ultra-stealth on a budget is the whole mission, it holds up. But the Go SRT is the version that fixes the ArGo's actual weak points. If you're choosing between them and budget allows, the Go SRT is the clear winner.

Owner's Guide: Getting the Most From Your Arizer Go SRT

That's the review. This is the part for once it's in your pocket — my own unit, plus owner emails and the threads of people who've had theirs longer than I've had mine. Most "it's weak" complaints about this device come down to one habit, and it's the first thing below. If you remember one sentence from this section, make it this one: the buzz means the chamber is at temperature, not your herb.

First Use & Setup

1. Charge it fully before the first session. USB-C Power Delivery at 5V/3A. Arizer quote one to three hours; a proper PD brick gets you the short end of that, a tired laptop port the long end.
2. Run two empty burn-offs at the top of the range. Glass aroma tube in, cap off, window open, and let it cool fully between the two. There's a faint hot-metal smell on the first cycle that doesn't come back.
3. First real session: something ordinary, in the glass tube, low. 0.15g, around 180°C. Glass is inert from the first second, so expect clean flavour straight away. If you taste plastic or anything acrid at this stage, that's a warranty conversation, not a seasoning one — though check it isn't the PVC travel tubes the stems ship in first.
4. Keep your proof of purchase. The warranty is genuinely good, but "lifetime" only means anything with a dated invoice from an authorised seller. File it the day it arrives.

Break the shells in on purpose. Sessions two and three, use the Go Shells and use them badly. Get the loading wrong in your own kitchen rather than in a pub garden with cold hands. The shell screen is press-fit and does not lock — you want to have discovered that at home. And don't judge flavour on the first bowl through a brand-new shell: new shells and screens carry a faint metallic edge for two or three uses, then it vanishes. It isn't the device and it isn't your herb.

Set your presets once, on day one. Twenty minutes, then close the menu and leave it. Each preset stores a temperature and a heat time, and that second number matters: 190°C for two minutes and 190°C for six minutes are two completely different bowls. Every experienced user has been compensating for that by feel forever; here it's a setting. Mine: a morning preset at 182°C with a short heat time for micro-sessions, and a main preset at 192°C with a four-minute heat time that does 80% of the work. Keep a hotter one for dense shells and water pipe sessions. If you find yourself reaching for the very top of the range regularly, your grind is wrong or your pack is too tight.

Loading & Technique

The packing basics are up in the vapour section — shells medium-fine and gently tamped, the tube medium and loose with 2mm of headroom. Here's why they matter more on this device than on a big-oven vape, and the habit that fixes most disappointing first draws.

Small oven, so grind matters more. Waste 15% of a large bowl and you've lost a draw; waste 15% of a 0.2g shell and you've lost a quarter of the session. With convection doing most of the work, hot air has to physically reach every particle: coarse chunks under-extract, the outside gives up its terpenes and the inside comes out green. Go to powder, though, and you clog the shell screen, choke the draw and channel the airflow down one side. Cracked black pepper, not sea salt and not dust — a shade finer for shells than for the tube. Too fine in the tube and specks drop through the open bottom onto the heater, which is where the occasional brief scorched note comes from. Skip electric blade grinders and grind fresh: dry, fortnight-open herb burns hotter and faster in a small chamber than in a big one.

Don't over-tamp. The most common Go SRT mistake. A firm shell pack is not an espresso puck — if the draw feels like work, you've packed too hard. And check the shell screen is sitting flat every time you load; a shifted screen channels the whole bowl.

The knack: count to ten after the buzz. The chamber genuinely reaches temperature in seconds. The herb doesn't. On a device with lots of thermal mass that gap barely matters, because the walls catch up mid-draw. In a small hybrid oven, drawing the instant the haptic buzzes means your first pull is doing the heating work the device should have done — thin draw, and you conclude the thing is weak. Wait ten seconds, no more. On a device sold on its fast heat-up that feels absurd. Do it anyway; it's the difference between a warm-up draw and the best hit of the session.

Draw slow — eight to twelve seconds. Long, lazy, low effort, like a milkshake through a wide straw. Hybrid convection through a narrow glass path punishes a hard pull: you drag cool air through faster than the heater can warm it. When density drops near the end, switch to quick one-to-two-second puffs — on a nearly spent 0.2g bed, short puffs remobilise what's left far better than a big drag.

Sunday night shell prep. Grind enough for four or five shells at once, pack them gently, and drop them in a shell case with the device. That's the week's out-of-house sessions sorted — no grinder in a jacket pocket, no packing a stem by phone torch on a towpath in February. Two rules: don't pre-pack more than about a week ahead (packed shells go stale faster than herb in a jar, because far more surface is exposed), and keep two strains in physically separate rows, because packed shells look identical. And charge the device when you pack the shells, not when you leave. Tom borrowed my kit for a weekend in the Peaks and brought it back with four of the five shells still packed and the cell completely flat. "I only used it once," he said, "but I kept getting it out to show people the cap."

Through water — use a shell. Fit the 14mm water pipe adapter and load a shell rather than the tube; the tighter airflow suits the extra draw resistance and the bowl finishes fully instead of leaving green in the middle. Bump your temperature 3–5°C over your dry setting to allow for the cooling and draw even slower. The display rotates when the device is flipped, so it stays readable on a bubbler. Plugged into a PD source at the desk, pass-through turns it into an effectively unlimited home setup.

Temperature Settings

This is a small oven, so the stepping is deliberately more aggressive than you'd run on a full-size device — less material and less thermal mass to play with. Here's how the range behaves on the Go SRT (full theory in our temperature guide):

Setting	What you get	When to use it
160–175°C	Raw, bright, grassy top notes; barely-there effect	Tasting a new jar; the first draw of the day
175–187°C	The full terpene profile — citrus, pine, pepper, dairy — notes kept separate	Morning micro-sessions, flavour chasing
187–197°C	Deeper, rounder, full spectrum; vapour thickens	Evenings, general use, consistent dosing — your main preset
197–210°C	Toasted, caramelised, heavier and more body-led	The end of the bowl, the end of the day
210–220°C	Burnt sugar and a harsh edge	Genuinely tired bowls only — reload instead

The stepping routine I actually run (after the ten-second soak):

1. Start at 182–185°C for two or three draws. This is where the top notes live and where you find out what you've actually got in the shell.
2. Step to 190–192°C at draw three — not draw five. The body of the strain arrives and most of the session's work happens here.
3. Step to 198–202°C at draw six. Density peaks.
4. Two draws at 205°C to finish, then stop. Short puffs, not long drags.
5. Check the ABV. Even mid-brown across the whole bed is the target. Green in the middle means you packed too tight or drew too hard; patchy dark spots mean an uneven pack or a shifted screen.

Eight or nine draws, ten to twelve minutes, shell spent. That's a complete Go SRT session — trying to stretch it to fifteen draws is how people end up disappointed.

Adjust for the jar. Fragile terpinolene sativas: start at 180°C, use the glass tube rather than a shell, and accept that the pine-and-lemon top end lives in the first two or three draws. Dessert hybrids and dense caryophyllene-forward flower: this oven's happiest place — use a shell and tamp gently. Limonene-heavy citrus: spend four draws at 178–184°C before you step at all. Myrcene-dominant indicas are the opposite errand — be at 195°C by draw four. Sticky, resinous flower wants a finer grind, a shell and more aggressive steps; dry or older herb wants the reverse — a touch more material, 5°C lower, slower draws.

Cleaning Schedule

The herb never touches the heater — it sits inside glass or inside a shell — so resin condenses on removable parts you can drop in a jar of ISO, and the oven stays essentially pristine. A full clean is about forty seconds of actual effort plus an unattended soak. General principles are in our cleaning guide; this is the Go SRT routine.

When	What to do	Time
Daily (after every session)	Tap the spent material out of the shell or tube while it's still warm; quick pass of the brush over the shell screen. Cap it warm.	Five seconds
Weekly (every 10–15 bowls)	Soak shells and tubes in 90%+ isopropyl for an hour, rinse in warm water, dry fully. Wash the cap and grip in warm soapy water every couple of weeks — they pick up smell long before resin.	An hour, unattended
Monthly (every 30+ bowls)	Longer soak, inspect the screens and replace any that are warped or won't come clean. Dry-brush the empty chamber.	Two hours, mostly waiting

The deep clean, step by step. Device off and completely cold. Remove the cap, the tube and any shells; if the screens are due for inspection, push them out gently from the underside (they're press-fit — never lever at them with anything metal). Soak everything in 90%+ isopropyl in a glass jar for an hour; plastic containers can leach into IPA. Pipe cleaner through the tube while it's wet, cotton bud round the inside lip of each shell. Rinse thoroughly in warm water — isopropyl residue tastes revolting and you'll notice it on the next bowl — then air-dry a full hour. Damp glass in a warm chamber gives you a strange first draw. The chamber itself only ever needs a dry brush, and once in a blue moon a cotton bud barely dampened with ISO, device off, cold, held upside down so nothing runs in.

Never: submerge the body (it's an aluminium tube full of electronics and a lithium cell); soak the silicone cap or grip in isopropyl (it degrades the silicone and you lose the snug seat); put glass in a dishwasher (it comes out cloudy and thermal shock cracks it); force a dislodged screen back with a fingernail while it's hot; or use anything but isopropyl.

Troubleshooting

Problem	Likely cause	Fix
Thin, weak first draw despite the fast heat-up	You drew on the buzz — the chamber is at temperature, the herb bed isn't	Count to ten after the buzz. This fixes more Go SRT complaints than everything else combined
Bowl channels; ABV green in the middle, dark at the edges	Shell screen has shifted, or the pack is too tight	Let the shell cool, reseat the screen flat, repack with a gentler tamp. Check the screen every time you load
Draw feels like hard work	Over-tamped shell, grind too fine, or a screen clogged with dust	Loosen the pack, coarsen the grind slightly, soak or replace the screen
Brief scorched or acrid note mid-session	Specks have dropped from the open bottom of the tube onto the heater	Tap the tube level before loading, leave 2mm headroom, brush the chamber. A classic Arizer trait, largely preventable
Session runs out by draw five	Started too low and never stepped	Step at draw three, not draw six. Small oven, early steps
Off taste after a clean, or metallic on a new shell	Isopropyl residue or damp parts; or new-part break-in	Rinse more thoroughly, air-dry a full hour, run one empty cycle. A metallic edge on new parts goes after two or three bowls
Fewer bowls per charge than you expected from new	High temperatures, shells rather than the tube, cold weather — or an eco setting capping the charge at 80%	Check the eco charge setting first. Genuine early battery fade is a warranty conversation — see the note below
Won't charge, or charges very slowly	Underpowered source, or a tired cable	Use a proper USB-C PD source at 5V/3A and try another cable before you suspect the port
Cap feels less secure than it did	Debris in the seat, or silicone degraded by isopropyl	Clean the seat, and stop cleaning the cap with IPA
A preset doesn't behave the way you expect	You changed its heat time, not just its temperature	Check both settings on that preset — the two together define the session
Display hard to read outdoors	Dark Mode is on	Switch Dark Mode off in bright light; turn it back on for the cinema

When the battery ages. The 21700 cell can be replaced, but not by you: Arizer's support say battery replacement goes through Arizer. So don't open the device, and don't buy any third-party "battery upgrade kit" — contact Arizer, or email us at info@herbvape.co.uk with your order number and we'll point you the right way. The same goes for any fault: order number, the device serial and a short video of the symptom saves a week of back-and-forth. The warranty is lifetime on the heating element, two years on the device and one on the battery. Drops, liquid damage and wear parts — glass, shell screens, silicone — aren't covered.

Storage and flying. Day to day: cap on, upright, out of direct sun — the cap keeps dust and kitchen grease out of the glass path as well as protecting it. For breaks of two weeks or more, empty the chamber and every shell and leave the cell around half charged; lithium cells stored full or flat age faster. Flying: a single 21700 sits far below the 100 Wh cabin limit, but it goes in your hand luggage, never the hold. Empty the oven and the shells, and cap it so it can't power on in the bag.

Parts & Accessories That Fit

One thing first: the Go SRT uses its own smaller stem format, and the Go Shells are exclusive to it. Solo and Air glass doesn't fit, so don't buy on the assumption it crosses over.

• More shells. The Go SRT Shell Pack (6x Go Shells) is the single addition that makes the device make sense: pre-pack a week's worth, never grind away from home, and never pick at a hot shell because there's a cool one ready. If you buy one thing, buy this.
• Somewhere to keep them. The Go SRT Shell Case. Packed shells rattling loose in a bag is how packed shells stop being packed.
• Spare glass. A spare Go SRT Mouthpiece. Glass breaks, and a spare saves an evening.
• Screens. The shell screens are the one real wear item — buy replacements before you need them. A warped screen mid-week is annoying out of all proportion to its cost.
• Cleaning. The HerbVape Universal Cleaning Kit covers the brushes and pipe cleaners for the soak routine above.
• Skip: a separate water pipe adapter (there's one in the box); aftermarket shells and screens from marketplace sellers (they don't seat properly, and a badly seated screen ruins a whole 0.2g bowl); "flavour-enhancing" glass tips (the path is already all glass and already short); and a silicone body case — essential on older Arizers with an exposed stem, redundant here, which is rather the point of the magnetic cap.
