A note before we start: my Go SRT review is a Week-1-of-6 first-impressions piece, and its 8.6 is provisional. That matters more here than in any other comparison on the site, because this head-to-head is a dead heat on paper — 8.6 apiece — and one of those 8.6s is backed by eight months of use while the other is backed by seven days. The full Go SRT update lands late September 2026. Until then, treat the tie as an honest snapshot, not a settled result.
30-Second Verdict
Nobody wins overall — 8.6 plays 8.6, one provisional — and the honest one-line truth is that this is the purest philosophy decision on the site: same glass, same flavour grade, very different prices, split entirely by how you want to feed the thing electricity. The Go SRT is the modern convenience package; the Air MAX is the swap-it-yourself forever machine.
- Go SRT: 8.6/10 (provisional, week 1 of 6)
- Air MAX: 8.6/10
Buy the Go SRT if:
- You want genuine pocket/handbag carry with the glass path sealed inside
- Fifteen-second heat-ups and pre-packed Go Shells fit how you actually go out
- You want USB-C PD, pass-through and a cell you can replace when it ages
- The complete kit in the box (WPA, shells, travel case) appeals
Buy the Air MAX if:
- You want field-swappable power — fresh 26650 in ten seconds, no charger, no mercy
- Festivals, gardens and long days off-grid are your actual use case
- You want 90% of the same flavour for a lot less money
- You like devices where every part that wears out can be replaced

The Hook: Contactless and Cash
There's a bloke in my local — you know him, every local has one — who still pays for everything in cash. Draws it out on a Monday, folds it into a worn leather wallet, and settles every round with actual notes. He's not a luddite. He'll tell you exactly why: cash never declines. Cash doesn't need a signal, a battery, or a bank's permission. When the card machine goes down and the whole pub queue seizes up, he's the one calmly putting a tenner on the bar.
Meanwhile the rest of us tap. Phone, watch, card, doesn't matter — a wave of the wrist and the transaction vanishes into the background of your life. Faster, cleaner, thought-free. Right up until the day the terminal says "card declined" in front of everyone, and there is nothing — nothing — you can do about it except stand there radiating heat.
The Go SRT is contactless. The Air MAX is cash. And Arizer, unhelpfully for anyone wanting an easy answer, has scored them exactly the same: 8.6 apiece.
Same brand, same borosilicate religion, same shared glass-stem ecosystem that makes the whole Arizer range feel like one modular family. The Go SRT is the tap-and-go experience: fifteen seconds to temperature, magnetic cap, shells pre-packed, USB-C PD topping it up in the background of your day. The Air MAX — Trigger's Broom, as I called it in its review, seventeen new heads and fourteen new handles — is the folded tenner: slower, chunkier, older-fashioned, and utterly incapable of declining. Battery flat? Pop in a fresh 26650, ten seconds, sweep on.
The scores can't split them. The price can, and by a clear margin. But the real decision was never money. It's which failure mode you refuse to live with.
We stock both at HerbVape.co.uk — details and pricing below.
Vapour Quality
Both score 9/10, and this is the least surprising tie in the building.
Both run all-borosilicate vapour paths. Both put nothing between you and the flower except glass and airflow. The differences are architectural, not qualitative. The Go SRT runs the 75/25 hybrid heater refined down from the Solo 3 — convection doing the extraction, a little conduction keeping things fast and consistent — with 5–15 second heat-up and the choice of tube or shell. The Air MAX is the classic Arizer arrangement: stem-in-oven, moderately restricted airflow somewhere between a joint and a milkshake straw, slow 10–15 second draws that reward patience.
In practice: the Go SRT is quicker to the first draw by a country mile and its shells concentrate the draw more tightly; the Air MAX's evenly toasted ABV and steady session pacing are as dependable as they've been for eight months. Neither device flatters the flower and neither one betrays it. If you handed me a blindfold and one draw from each at matched temperatures, I'd be guessing off draw resistance, not flavour.
Winner: dead heat — pick your architecture, not your terps.
The Strain Test, Side by Side
Same jars, same grinder, same running order — and for once, near-identical loads: 0.2g in the Go SRT's tube and shells, 0.15g in the Air MAX's stem. Ladders differ slightly (Go SRT at 180/190/200°C; Air MAX at 175/190/200°C), so compare stages, not degrees.
Jack Herer
Both devices pass Jack's three-second ambush. On the Air MAX, the pine reads on draw one exactly as it does out of the jar — pine needles and lemon peel intact, a cooling mint edge the glass keeps sharp. On the Go SRT, same story: pine properly there, no off-notes, because there's nothing in either path to contribute any.
Both also run out of Jack early, and for the same reason: small ovens. On the Air MAX, black pepper cuts through on the second draw of the mid stage — earlier than I'd like — and the citrus hands over to woody haze within a draw and a half. Eleven draws, about thirteen minutes. On the Go SRT, the lift thins by draw three of the low stage and the pine is a memory by the end of the mid stage. Eight draws, eleven minutes. My review lines for each were nearly interchangeable: the Air MAX is "a broom with a shorter handle"; the Go SRT "renders Jack accurately for about half the session and then runs out of road."
The side-by-side conclusion: on the fragile strain, these two are the same machine wearing different coats — total fidelity, limited duration, and if you want Jack's full terpinolene arc, the answer for both is the same: buy more oven upstream. The one fresh distinction worth making is pace: the Air MAX's restricted stem stretches its shorter window across more, slower draws, while the Go SRT gets you the same window quicker and lets you cap it and leave.
Wedding Cake
The dessert strain suits both small chambers, and here the shell earns its keep. On the Air MAX, Wedding Cake comes out "legible and slightly lean" — vanilla, cream and dough as three nameable things, butter and baked cake at the mid stage, defined dessert rather than luxurious dessert. On the Go SRT, the Go Shell's tighter draw concentrates the profile — the same separated layers, but denser in the mouth, and my review called it the strain that "fills the plate."
Fresh comparative observation that follows from both write-ups: Wedding Cake is where the two diverge most, and it's entirely down to airflow — the Air MAX gives you the strain well-lit and airy through the open stem; the Go SRT's shell gives it to you pressed and concentrated. Same kitchen, one plates it as a tasting portion, the other as a slice.
The flavour-device call: both are flavour devices, full stop — on each, the two strains still read as two different plants at 200°C. This pairing is the rare head-to-head where the flavour section decides nothing at all. Everything below it decides everything.
Design & Build
Go SRT: 8.5/10. Air MAX: 8.5/10. Even the build scores refuse to pick a side.
The Air MAX is the flashlight: anodised aluminium, boringly solid, the device that survived Jake dropping it onto festival hardstanding from waist height without a scratch. Its weakness is the exposed glass stem — pint glasses, as the review put it — and battery cap threads that get gunky and throw weird charge readings until you wipe them with ISO.
The Go SRT is the same aluminium confidence in a shorter, denser package (237g to the Air MAX's ~160g — the small one is the heavy one, oddly), and its party trick is the magnetic On-The-Go Cap that seals the glass inside the body. That single feature deletes the Air MAX's biggest structural vulnerability: there is no exposed stem to snap, ever. Its own quirk is the Go Shell screen that doesn't lock in place — a design wrinkle you stop noticing by session three.
Honesty clause: the Air MAX's 8.5 has eight months and one concrete drop behind it. The Go SRT's 8.5 has one week, and magnet wear is on the 6-week checklist.
Winner: Go SRT on design, Air MAX on proof. Ask me again in September.
Battery & Charging
Go SRT: 8.5/10. Air MAX: 9/10. This is the entire article. Everything else is garnish.
The Air MAX is cash. Removable 26650s — retailers put them around 5500mAh — swapped in ten seconds with your thumb, 4–5 bowls per cell at my temps, roughly an hour of session time each. Carry two for an evening, four for a festival day. I've run four cells across a twelve-hour, sixteen-bowl Saturday and the device never once stopped. Sarah walked past mid-marathon and asked why I had four batteries in my pocket. I still don't have a good answer. USB-C, ~90% in two hours, pass-through supported.
The Go SRT is contactless. One 21700 inside, 10–14 bowls per charge — two to three times the per-cell endurance of the Air MAX — USB-C PD refilling it in about 90 minutes measured, pass-through for desk days. And, crucially, the cell is replaceable with basic tools. That's the detail that keeps the Go SRT out of the sealed-battery landfill trap — Amit's three sealed-battery devices died on him across two continents, physics not luck, and the Go SRT dodges that fate. But be precise about what "replaceable" means on each: the Go SRT is a screwdriver-and-kitchen-table job; the Air MAX is a ten-second swap in a muddy field. One protects your investment. The other protects your afternoon.
So: more bowls per charge, faster charging, modern convenience — Go SRT. Infinite runtime anywhere on earth with a pocketful of spare cells — Air MAX. When Dave's Crafty+ died at a festival last summer, it was the Air MAX and three spare cells that rescued him, and he'd bought his own within the week. No sealed or semi-sealed device can tell that story.
Winner: Air MAX, by the width of a card machine going down.
Ease of Use
Air MAX: 9.5/10. Go SRT: 8/10. The old machine wins this one comfortably.
The Air MAX is the vape I handed to Sarah with zero instructions for her first-ever draw — set to 185°C, "draw slowly," thirty seconds later: "That's it?" Yes. That's it. No app, no presets, no philosophy. Buttons, a screen, single-degree steps, done. Your nan could use it.
The Go SRT's V-Scale system (Gentle, Balanced, Intense, Extreme) is genuinely smarter — volatilisation profiles rather than bare degrees — and genuinely more to learn. Two or three sessions and the logic clicks; by day three you've customised your two presets and forgotten the rest. Add the shell screens' careful-handling quirk and the hot-shell silicone-grip dance, and week one has more friction than the Air MAX has in its entire manual.
Winner: Air MAX — simplicity is a feature, and it has nothing but.
Cleaning & Maintenance
Both score 9/10. Same religion, same ritual: the glass (and shells) are the only parts that gunk up, the ovens stay pristine, ISO does the rest in about forty seconds. The Air MAX adds a monthly wipe of the battery cap threads; the Go SRT adds shell screens as a small annual consumable. Compared to a Mighty+ cooling-unit teardown, both are a rounding error.
Winner: tie, and a well-earned one.
Portability
Go SRT: 9/10. Air MAX: 8/10.
The Air MAX is a slim cylinder that travels well — coat pocket, bag, festival — but the stem sticks out the top and needs protecting, and the spare cells add pocket bulk. The Go SRT caps its glass inside the body and disappears into a handbag or proper jeans pocket, no anxiety, no case required. The going-out slot is why the Go SRT exists; the Air MAX's slot is the long day out, not the discreet evening.
Winner: Go SRT — though note the Air MAX gives up less here than most rivals do.
Value for Money
Air MAX: 8.5/10. Go SRT: 8/10 — and the price gap is the biggest number in this article.
The Air MAX's price buys its entire forever-device proposition: same flavour grade, field-swap power, replaceable everything. The Go SRT's price buys the complete modern kit — WPA, shells, travel case in the box, PD charging, the magnetic cap, lifetime heater warranty against the Air MAX's plainer 2-year limited term. The Go SRT's warranty and completeness genuinely narrow the gap; they don't close it.
If the price gap matters to you, the Air MAX is the answer and you should not feel you've settled — its own review called it exceptional value, and nothing in the Go SRT's first week changes that. The Go SRT is what you pay for when the extra money buys hours of your actual life back: heat-ups, pre-packed shells, a bag you don't worry about.
Winner: Air MAX.

Three ties, two wins each. I promise I didn't plan that. Neither, presumably, did Arizer.
Who Should Buy Which
The going-out user buys the Go SRT. If your vaping happens in restaurants, cinemas, other people's houses and the walk between them, the fifteen-second heat-up, the sealed cap and the Sunday-night shell-packing ritual are worth every penny of the premium. This is the Arizer built around leaving the house, and nothing else in the range — nothing else at this size from anyone, frankly — does the glass path this conveniently.
The off-grid user buys the Air MAX. Festivals, gardens, camping, twelve-hour days nowhere near a socket: this is the one use case where the Air MAX doesn't just compete with the Go SRT, it beats it outright, because a screwdriver-swap cell is no use in a field and a pocketful of 26650s is. It's also the answer for anyone who reads "cheaper, same flavour score" and rightly wonders what the rest of the argument is for.
The undecided buy on battery philosophy, because that's genuinely the whole split. Contactless: one cell, charge it like a phone, replace it every couple of years with a screwdriver. Cash: many cells, charge them in a bay, swap them like magazines. Both philosophies end in the same vapour. And whichever you choose, you're buying into the same glass ecosystem — which makes owning both, eventually, the most Arizer outcome of all.
How I Actually Choose
Both are in my rotation, doing jobs that barely overlap.
The Air MAX is my garden and festival device — 2–3 times a week, more in summer, four 26650s in rotation, two always in the charger, and yes, the battery-cycle spreadsheet Sarah has seen and has concerns about. It's the Saturday marathon machine and the one I hand to people, because it survived Jake and concrete and it'll survive anyone.
The Go SRT — one week in, provisionally — has taken the leaving-the-house-for-more-than-two-hours slot: shells pre-packed, Balanced preset at 192°C, travel case in the jacket. Different doors of the same house, essentially: the Air MAX goes out the back door into the garden, the Go SRT goes out the front door into town.
Dave's contribution, by text, within an hour of hearing I had the Go SRT in: "Does it take my batteries?" No, Dave. It's a 21700, and it wants a screwdriver. There was a long pause, and then: "So it's not a real one, then." That's the whole debate in two texts from a man who's owned an Air MAX since his Crafty+ died in a field.
The Verdict (The Bookend)
The bloke with the leather wallet isn't wrong, and neither are the rest of us tapping our watches at the bar. Cash never declines; contactless never fumbles. You don't settle that argument — you just notice which failure you personally cannot stand, and you carry accordingly.
8.6 plays 8.6. Same glass, same honesty, one price bracket and one battery philosophy apart. If your vaping life happens away from plug sockets for whole days at a stretch, buy the Air MAX and never think about power again. If your vaping life happens in town, in bags, in fifteen-second windows, buy the Go SRT and let the charging happen in the background of your life.
And the asterisk, stated plainly: the Air MAX's 8.6 is eight months settled. The Go SRT's is a week old. If the honeymoon ends, the late-September update will say so — and so will this page.
FAQ
Go SRT vs Air MAX — which should I buy?
Same overall score (8.6, the Go SRT's provisional), same 9/10 flavour. Buy the Go SRT for town: pocket carry, 15-second heat-up, pre-packed shells. Buy the Air MAX for off-grid: ten-second 26650 swaps and infinite runtime. Battery philosophy is the whole decision.
Are both batteries replaceable, then?
Yes, but differently — and the difference matters. The Air MAX's 26650 is a true field swap: thumb, ten seconds, done. The Go SRT's 21700 comes out with basic tools at a table — it protects the device's lifespan, not your afternoon in a field.
Which lasts longer per charge?
The Go SRT: 10–14 bowls per charge against the Air MAX's 4–5 per cell. The Air MAX answers with spares — two cells for an evening, four for a festival day.
Do they share stems and batteries?
Batteries, no — 21700 versus 26650, not interchangeable. Glass-wise they're both all-borosilicate Arizers with their own stem formats (Go Shells and tube versus Air-family stems), and the wider Arizer accessory ecosystem is part of both devices' appeal.
Can I use either with a water pipe?
The Go SRT ships with a 14mm WPA in the box, and the shells suit water-pipe draw resistance. The Air MAX takes the Arizer glass elbow adapter, sold separately.
Which is easier to keep clean?
Both trivially easy — ISO-soak the glass, done in under a minute. The Air MAX asks for a monthly battery-thread wipe; the Go SRT gets through a few shell screens a year.
Why is the Go SRT's score provisional?
It's a week-one review of a just-launched device. Reliability, battery degradation and magnet wear need the full six weeks. Update due late September 2026 — and this comparison will be corrected with it if needed.
About Dennis M.
Dennis M. has been vaping daily for the best part of a decade — since an original Mighty in 2018 — and has tested 50+ devices for this site. He works in IT, has ADHD, and uses cannabis for chronic pain management. He lives in Manchester with his partner Sarah, who has seen the battery-cycle spreadsheet, has concerns about him as a person, and has now watched him buy a second Arizer that needs a completely different battery.
Dennis owns four 26650s, a four-bay charger, and — as of last week — one 21700 he cannot swap in a field. He maintains this is a coherent system. Dave disagrees, by text, at length.
A note on spelling: 'vaporizer' is the de facto international spelling, but I've stuck with the British 'vaporiser' throughout this blog.
