Storz & Bickel Mighty+ Review & Owner's Guide (2026): Tested, 8.7/10

The Hook: The Land Rover Defender

Your mate pulls up in a Range Rover Sport. Glossy black, air suspension, looks like it was designed in a wind tunnel. Cost him seventy grand. Triple the power of anything he actually needs. And every time it goes in for a service, there's a new warning light, a new software update, a new reason to be slightly anxious about what might go wrong next.

Then the farmer next door rumbles past in a Defender that's older than you are. Mud on the wheel arches. Dents in the panels. A dog in the back that's seen more fields than most people see in a lifetime. That Defender's been starting every morning since 1987. It'll be starting every morning long after the Range Rover Sport's been traded in for something newer and shinier.

But when you actually need to get somewhere — through mud, through snow, through a farm track at 5am in February — the Defender's the one you trust.

That's the Mighty+. And the Range Rover Sport? That's the Venty. Same manufacturer. Same German engineering pedigree. Very different philosophies. The Venty is the flashy one — faster heat-up, triple the airflow, Bluetooth app control. Genuinely brilliant when it's working. But there's that constant low-level anxiety. Early batches had QC issues. Error codes pop up. You find yourself checking forums to see if your serial number is in a 'good' batch.

The Mighty+ is the Defender. Chunky. Boring. Been doing this for twenty years. Storz & Bickel's entire reputation distilled into a plastic rectangle that does one thing brilliantly: extract cannabinoids from plant matter and deliver them to your lungs without making you think. Without making you worry.

We stock the Mighty+ at HerbVape.co.uk — details and pricing above. Already own one? The owner's guide further down covers setup, the best temperatures, cleaning and fixes.

Vapour Quality 9.0/10

Let me be honest about the missing point: on-demand devices like the TinyMight 2 extract more initial flavour from those first low-temp draws, and the Venty moves significantly more air. If the category were 'Vapour Consistency,' this would be a 10. But it's Vapour Quality, and quality includes extraction power, airflow, and density — areas where other devices genuinely edge ahead. What earns the 9.0 is that nothing matches the Mighty+ for showing up the same way, every time, without asking anything of you. No technique. No learning curve. No combustion risk. Bowl after bowl.

Convection for flavour, conduction for consistency — and the cooling unit earns its keep by making everything feel gentler than it has any right to. First draw at 180°C: smooth, cool, flavourful. That classic S&B experience people have been banging on about for two decades.

This isn't a ripper. Let me be clear about that. If you're coming from massive bong hits and expecting to clear a bowl in two monster draws, the Mighty+ will disappoint you. This is a sipper. It's the difference between doing shots and nursing a pint. You're getting 5-12 draws over a 5-10 minute session, spread across 10-15 minutes of gentle toking. More joint than bong. More session than sprint.

At 180-185°C, the flavour stays bright and terpy through the first few draws, then settles into that fuller-bodied middle section before you step up the temperature to finish extraction. I usually cruise at 180°C, step to 190°C halfway through, then boost to 200°C for the last couple of hits. By then the terps are mostly gone and you're just squeezing out the last cannabinoids, but that's fine — the first half of the bowl is where the magic lives.

That's worth more than people realise.

The Strain Test

A Defender doesn't get to choose the terrain, so the terrain stays fixed: same two jars, same grinder, same weights, with the strain doing the testing and the machine the only thing being tested. The Defender's question is whether something built never to let you down can also be trusted with something fragile. Cooling unit stripped and swabbed between the two, as always.

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: 0.18g, medium grind, loose in the chamber, no capsule, cold load onto a cold oven.

Low Temp (180°C): Pine on draw one, but softened — the chamber walls and that oversized cooling unit take the needle-point off it before it reaches you. Warm pine rather than fresh pine. Lemon peel sits underneath it, faint but legible, and there's dry green herb behind both. Five draws at this stage and the citrus lift is still detectable on the fourth, which is a better result than most session devices manage. It never sparkles. It also never falters.

Mid Temp (190°C): Black pepper turns up on the first draw of this stage and it is properly defined — this is where the hybrid heater stops apologising and starts working. The haze goes woody, dry, faintly incense-like, and the citrus finally dies somewhere around draw six overall. Four draws here, each one denser than the last, all of them smooth enough that you forget you're at 190°C. The cooling unit is doing the heaviest lifting of the session.

High Temp (200°C): Earth and leather, with a light fuel note underneath and a savoury roast creeping in behind that. Three draws and the ABV is an even mid-brown. No scorch anywhere, which is the whole point of this machine.

The Verdict: Jack survives the Defender rather than shining in it. Every note that's supposed to be there is there, in the right order, at the right stage — but the same rounding that makes this device smooth also sands the top off the terpinolene, so you get a good pine instead of a great one. That is the honest cost of the cooling unit, and it is the one thing keeping this off a 10 for vapour. What you get in exchange is that all twelve draws were the same twelve draws I'd have got last Tuesday. The Defender doesn't care what you load. It just doesn't do delicate.

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, medium grind, dosing capsule this time — the greasy stuff makes a mess of a bare oven and the capsule saves ten minutes with a brush later.

Low Temp (180°C): Vanilla and sweet cream straight out of the gate, thick enough that you can feel the weight of it on the tongue. Sweet raw dough underneath by draw two, and a cherry edge that shows up on the exhale exactly where the jar said it would. Five draws, all of them smooth and cool, none of them harsh. This is the cooling unit's finest hour.

Mid Temp (190°C): Butter shows up alongside the dough and — this is the part that matters — it stays a separate thing. Vanilla, butter, warm baked cake and the first of the black pepper, four distinct items rather than one undifferentiated sweet. Four draws, dense and heavy. Sarah, who calls this thing the brick, walked through the kitchen at this point and asked whether I'd been baking.

High Temp (200°C): Toasted and nutty, the sugar caramelising toward a burnt edge, pepper turning pungent underneath. Two draws is all this stage needs; a third and you're just heating spent leaf.

The Verdict: This is what the Defender was built to haul. Wedding Cake is a heavy, robust, dessert-genetics load and the Mighty+ handles it the way it handles everything — thoroughly, evenly, without drama — except that here the rounding-off is a gift rather than a tax. Vanilla stayed vanilla, butter stayed butter, and I could still tell them apart at the top of the range. Put the two strains side by side at 200°C and they were still obviously two different plants: Jack in leather and light fuel, this one in caramelised sugar. That is a flavour device, not just a delivery device. It's simply a flavour device with all the corners filed off.

Design & Build (The 'Disaster' Story) 9/10

I knocked my Mighty+ off the kitchen counter while making tea. Classic Dennis move. Reached for the kettle, elbow caught the edge of the vape, and I watched it tumble in slow motion onto the tile floor.

Picked it up. Turned it on. Still worked. Not a scratch.

This thing is built to survive your lifestyle. And it does. The body is PEEK plastic — polyether ether ketone, the same high-performance thermoplastic they use in medical devices and aerospace. The vapour path is entirely PEEK too: no plastic taste, no off-gassing. Medical-grade engineering that happens to look like Fisher-Price. At 230g and 140 × 84 × 30mm, it's chunky but purposeful — every millimetre of that bulk serves a function. The extra girth houses the dual-battery pack and that oversized cooling unit, which is why the vapour comes out as smooth as it does.

The cooling unit clicks on with a satisfying snap. The OLED screen is bright and readable in any light, showing current and target temps without needing to squint. Two buttons handle everything: up and down. No touchscreen, no swipe gestures, no app required for basic operation. It vibrates when it hits temperature, which matters more than you'd think — you can load it up, set it down, and walk away until it buzzes.

What people don't mention enough is how the Mighty+ feels after a year of daily use. The rubberised grip doesn't degrade. The buttons don't get mushy. The screen doesn't develop dead pixels. The cooling unit latch doesn't loosen. Two years into mine and the only visible wear is a slight discolouration on the chamber rim from heat cycling — cosmetic, not functional. Everything says 'German engineering by people who've actually used vaporisers.' Your mate with the wooden TinyMight 2 will take the piss. Let them. Their vape needs technique and care; yours needs nothing but a charge.

Is Yours Real?

Counterfeit S&B portables are a genuine problem on grey-market marketplaces — the factories that cloned the original Mighty clone the Mighty+ too. Bought from an authorised UK dealer, this is a two-minute sanity check rather than something to lose sleep over:

• Chamber O-ring is blue. Documented fakes have shipped with a red one. Red means stop and ring your seller.
• The back sticker is semi-gloss, centred, cleanly printed. Fakes run matte, pale and slightly squint.
• The cooling unit's cap lock carries a 3D holographic S&B logo. Fakes either omit it or print a flat, muddy imitation.
• Seams are tight and the buttons sit right. More than one fake has turned up with the power button fitted upside down.
• It's dense and it doesn't rattle — and a real PEEK vapour path is tasteless from session one. Still tasting hot plastic after two full burn-offs? It isn't PEEK.

There's no public serial lookup, but registration at storz-bickel.com only goes through on a genuine device — and it takes your warranty from two years to three. Do it the day it lands; the window is 30 days and nobody remembers on day 29.

Battery & Charging 8/10

Real-world numbers: 6-8 bowls at my usual temps (180-190°C). If you're hammering it at 210°C with long sessions, closer to 4-5. Light, gentle sessions at 175°C, you might stretch to 10. An eleven-hour Lord of the Rings extended-edition marathon (Sarah was away, don't judge me) required two charges.

Here's where it gets important: the USB-C charging is brilliant, but there's a catch. With the S&B Supercharger — sold separately, which is a cheek at this price — you're looking at around 80% in 40 minutes and just over an hour from empty to full. With a standard phone charger? Four hours. Actually slower than the old barrel-port charger on the original Mighty.

One feature I use constantly is Boost — double-tap the power button and you get an instant +15°C for 90 seconds. Triple-tap and you're into Superbooster, another +15°C on top for +30°C total. It's perfect for finishing bowls or when you want to end a session strong. Max boost takes you to 210°C regardless of starting point.

Now, the elephant in the room: the pair of 18650 cells inside are not a user swap. This is the thing that makes people hesitate. You can't pop in fresh cells like you can with a TinyMight 2. When the battery eventually degrades — and it will, because that's what lithium cells do — you're looking at an RMA or a DIY replacement that voids your warranty. You're on a timer from day one.

In practice? Most people get years of solid use before battery degradation becomes noticeable. The sealed battery is the trade-off you make for a simpler, more water-resistant design. For daily use, you charge it overnight like a phone. For multi-day trips, you bring a power bank. It's not ideal. But it's not the dealbreaker the forum threads make it sound like either.

On the spec sheet: 2× 18650 cells, USB-C charging, ~80% in 40 minutes with the Supercharger, limited pass-through capability (don't rely on it), and no user-replaceable battery.

Ease of Use 9/10

Turn it on. Set your temperature. Wait about a minute. Draw.

That's it. That's the whole process.

There's no technique to master, no learning curve to climb, no risk of combusting because you held a button wrong. The Mighty+ is idiot-proof in the best possible way.

The interface is two buttons. Up, down, that's your lot. No app, no Bluetooth, no firmware, nothing to pair. The screen shows your current temp and target temp. When it vibrates, you're ready. Start sipping.

Loading is equally simple: grind your herb to medium, pour 0.15-0.2g into the chamber or a dosing capsule, light tamp if you want, done. Don't overthink the pack — the Mighty+ is forgiving. It doesn't need perfect technique to deliver.

Temperature stepping is intuitive. Start at 175°C, click up to 185°C after a few draws, boost to 200°C+ at the end. Or just set it to 185°C and leave it there. Both approaches work (the temperature table in the owner's guide below has the full plan). The Mighty+ doesn't punish you for being lazy. It also handles concentrates in a pinch — S&B liquid pad, max temp, very small amount. Not a dab rig replacement, but it works.

This is the vape I hand to first-timers. This is the vape I'd give to my mum if she needed it for her arthritis. It asks nothing of you except patience and the ability to press a button.

Cleaning & Maintenance (The 'Gunk' Confession) 5/10

Right, here's where we get properly honest.

The Mighty+ cooling unit is a gunk magnet. After about 20 bowls, you're looking at a sticky brown maze of reclaim that needs dealing with, and dealing with it is not fun.

Everything accumulates in the cooling unit. The little maze where vapour snakes through, the screens, the corners around the O-rings — it all gets coated in sticky tar that starts golden and turns properly brown if you ignore it. After 5-10 bowls you'll see the first brown lines appear but it's still fine. By 15-20 bowls the draw resistance increases and the flavour gets heavier. Push past 30 bowls and you're doing a proper teardown whether you want to or not.

The process itself is straightforward if tedious: strip the cooling unit, soak the hard parts in isopropyl alcohol, excavate the maze with cotton buds and toothpicks, dry, reassemble. Two pieces must never go in the soak, and the full step-by-step is in the owner's guide cleaning section below. Try not to lose any O-rings down the drain.

For the oven: brush it out after every bowl. Seriously. Get into the habit. Dump the ABV, brush the screen, move on. If you do this religiously, you'll extend the time between proper CU teardowns. The ceramic coating on the Mighty+ chamber helps — it stains less visibly than the old aluminium version.

Cleaning is the price you pay for that cooling unit magic — and it's a real price. Here's the thing people don't tell you: dosing capsules don't keep the device much cleaner. They help with the oven, sure, but the cooling unit still gets gunked because that's where the vapour condenses. Capsules are convenience, not a cleaning solution.

One last thing: keep spare cooling units. Rotate them. Use one while the other soaks. Your life becomes significantly easier.

If you want the step-by-step rather than the confession, the full cleaning routine and troubleshooting table are in the owner's guide below.

Portability 6.5/10

Let's not pretend: the Mighty+ is not a pocket vape.

It fits in a jacket pocket. It fits in a bag. It fits in the kind of cargo shorts your dad wears on holiday. But it's not slipping into your jeans and disappearing. At 230g it's chunky. It's obvious. It's a brick.

For home use? Irrelevant. You're not carrying it anywhere.

For the commute or a night out? It's doable, but you're planning around it rather than forgetting it's there.

For festivals or travel? It works, but you're packing a case and treating it like the premium piece of kit it is.

Stealth is non-existent. The vapour is thick and lingers. The device itself looks like medical equipment. Nobody's mistaking this for a vape pen or a USB stick. If discretion matters, the Crafty+ exists for exactly that reason. Or the ArGo if you want to disappear entirely.

How I Actually Use This

My default setup is 185°C, sometimes stepping to 190°C halfway through, with 0.15-0.2g loosely ground and no capsule. Sessions run 12-15 minutes across 5-12 draws depending on how slowly I'm sipping.

I reach for it most nights. Pain management sessions. This is the one that lives on the kitchen counter — about 30% of my total vape usage — it was 60% before the Solo 3 v2 arrived. I load it up around 8pm, usually get through 2-3 bowls, then leave it out for the next morning's session. It's the device that gets used when it matters, not the novelty device that gets rotated out.

When I don't reach for it: if I'm leaving the house, the Crafty+ lives in my backpack — smaller, more discreet, less obvious. The Mighty+ goes out occasionally, but if I'm genuinely mobile (commute, errands, going out out), the Crafty+ is the move. For weekend flavour sessions, the TinyMight 2 comes out when I'm deliberately chasing terps and have time to fiddle with technique. It hits differently at low temps, and that matters when you're actually paying attention.

The honest cleaning reality: I should clean the cooling unit every 20-30 bowls. I actually do it every 30-40 bowls when the draw resistance gets annoying enough to force my hand. The hot Q-tip method between deep cleans helps. I rotate between two cooling units, which makes the faff more bearable. Yes, I've definitely hit the point where I can taste the reclaim and still used it another few sessions because I couldn't be bothered with disassembly. We're all human.

I use this daily. Multiple bowls. This isn't aspirational writing — this is the device I have used every single day for two years except during the one week I was genuinely ill and wasn't vaping anything.

Medical Use Notes

For Pain Management: The session style is exactly what sustained pain relief needs. You're not getting one enormous hit and then a cliff drop in effects. You're getting 10-15 minutes of gentle, consistent cannabinoid delivery across 5-12 draws. That works for pain. The body absorbs it gradually. The effect is more stable than you'd get from a quick rip on a ripper device. For daily medical use, boring reliability beats exciting fragility every single time.

For ADHD: Low-temp microdosing is possible (175°C, small pack, 2-3 draws). It works. But that's not what I use it for — my main medical use is pain. If ADHD microdosing was primary, I'd reach for something with faster heat-up and on-demand capability.

Session Timing: First draw to noticeable pain relief: 3-5 minutes. Duration: 2-3 hours depending on strain and tolerance. Load at 8pm, session until 8:15, relief through to bedtime.

The Medical User's Concern: When something is your daily medical device, reliability matters more than novelty. Same experience every time. No firmware updates, no app bugs, no error codes (touch wood). The cleaning burden IS harder when you're fatigued from pain — keep spare cooling units and rotate, so you're never doing a full teardown when you're hurting.

What Other Owners Say

I'm one bloke with one kitchen counter, so here are two owners who aren't me — one medical, one ex-smoker.

Personas are composite profiles based on community feedback and owner correspondence, not individual testimonials.

Value for Money 8/10

This is premium money for a portable vaporiser. You could buy an XMAX V3 Pro for a fraction of the price and get 85% of the experience. You could buy a Solo 2 MAX for about half the money and get arguably better flavour with easier cleaning. You could save up a bit more and get a Venty with better airflow and faster heat-up.

But here's the thing: the Mighty+ has twenty years of Storz & Bickel reputation behind it. Not twenty years of this exact model, obviously, but twenty years of the company making medical-grade vaporisers that work. That's worth something.

When you buy a Mighty+, you're buying into an ecosystem refined over decades. The warranty is solid. The accessories are mature. The resale value holds. The troubleshooting knowledge base is extensive. You're not pioneering anything; you're joining a very large club of people who've already figured out all the tricks.

Would I pay full price again? Yes. Have I recommended it to friends? Yes — four of them tried mine and bought their own. Is it the best value in vaporisers? No. But 'best value' and 'safest choice' aren't the same thing. The Mighty+ is the safe choice, and for a lot of people, that's exactly why they buy it.

The Verdict (The Bookend)

Two years in, I still reach for the Mighty+ most nights.

The Defender doesn't have air suspension. It doesn't have a touchscreen infotainment system. It doesn't have adaptive cruise control or lane-keeping assist. It's a boxy thing that looks mildly surprised to still be starting after all these years.

But it's still in that barn. Still doing the job. Still the one the farmer reaches for at 5am when the sheep need moving.

The Mighty+ is the same. Boring. Reliable. The benchmark.

My mate Dave's been through five Mighty+ units in two years — not because he's clumsy, just error code lottery. Every single one got replaced under warranty within a week. Every single replacement worked perfectly until it didn't. That's not a great look for S&B quality control, and I won't pretend otherwise. But Dave's still using a Mighty+. He tried a TinyMight 2 for a month and came back. 'Too much faff,' he said. 'I just want to press a button and vape.'

That's the Mighty+ in one sentence. You just want to press a button and vape.

Some things don't need to be exciting. They just need to work.

Score Breakdown

Category	Score	One-Line Summary
Vapour Quality	9.0/10	On-demand devices extract harder and the Venty moves more air — but nothing matches this for consistency
Design & Build	9/10	Survives anything you throw at it (or drop on it), PEEK plastic is medical-grade
Battery & Charging	8/10	6-8 bowls per charge, fast charging is brilliant with the Supercharger
Ease of Use	9/10	Two buttons, zero learning curve, first-timer approved
Cleaning & Maintenance	5/10	The cooling unit is a full-time job nobody applied for
Portability	6.5/10	Jacket pocket at best, zero stealth, the brick nickname is earned
Value for Money	8/10	Not the cheapest, but the 'safe money' in a market full of gambles
Overall	8.7/10	The safe choice, and the one I still recommend first

Category average is 7.8. The overall sits above it because vapour quality and ease of use matter more than portability for a home session vape — and the cleaning score is what keeps this from a 9.

Vs the Competition

Mighty+ vs Venty

Same manufacturer, radically different philosophy. Triple the airflow, 20-second heat-up, Bluetooth app control — but dearer, more QC concerns, and more forum-checking anxiety. The Mighty+ just works. That difference compounds over years.

Full comparison →

Mighty+ vs TinyMight 2

Different tools entirely. The Mighty+ sips across 10-15 minutes; the TinyMight 2 rips through a bowl in 1-2 hits. The TinyMight 2 hits harder with swappable batteries and costs more; the Mighty+ is smoother and idiot-proof. Most people who own both use the Mighty+ more often.

Full comparison →

Mighty+ vs Crafty+

Same heating system, smaller body, smaller battery (4-5 bowls vs 6-8). The Crafty+ is the portable compromise; the Mighty+ is the home daily driver, and dearer for the privilege. You wouldn't regret either — they're aimed at different use cases.

Full comparison →

Mighty+ vs Solo 3 v2

The Solo 3 v2 heats in about 20 seconds with a pure glass vapour path that's a doddle to clean. Flavour purists will argue it edges ahead at low temps. But the Mighty+ is more forgiving, produces denser clouds, and doesn't shatter when your clumsy mates get involved. The Mighty+ is the dearer of the two.

Full comparison →

Mighty+ vs Legacy Pro 2

AirVape's hybrid response to the Mighty+'s session-king crown. Noticeably cheaper, with a removable 18650 battery, an on-demand mode the Mighty+ doesn't offer, and 1-degree temp control. The Legacy Pro 2 wins on flexibility, feature spread, and long-term battery economics; the Mighty+ wins on thoroughness, durability, and zero-friction operation. They finish on the same overall score, which is not a fudge — it's two genuinely different routes to the same standard. If you want one vape that just works forever, Mighty+. If you enjoy tweaking and want a removable cell, Legacy Pro 2.

Owner's Guide: Getting the Most From Your Mighty+

Everything above is about whether to buy one. This bit is for after you have. It comes from two years of daily use on my own unit, plus the emails and forum threads of a few hundred other owners. The Mighty+ is annoying in exactly two places, the cooling unit and the charger, and neither is a surprise once you know about them. Nearly every other complaint ("weak vapour", "it keeps switching off", "it tastes burnt") is a technique or maintenance problem, and you can fix it in a couple of minutes.

First Use and Setup

1. Charge it fully first. With a 45W USB-C PD charger you'll see roughly 80% in 40 minutes. The supplied cable on an ordinary phone plug takes about four hours, so use a decent laptop charger if you own one.
2. Run an empty burn-off at 210°C. Fit the cooling unit, leave the chamber empty, and let it run until it shuts itself off. Open a window, because there's a faint new-device smell on the first burn that never comes back. Run a second one if you're fussy. After that, a small throwaway load at 185°C and it's fully dialled in by session three to five.
3. Grind medium and load 0.15–0.2g loosely. Settle it, don't compress it (more on this below).
4. Hold power, set 185°C with the up/down buttons, and wait. It takes about 60 seconds from cold.
5. First vibration: don't draw yet. Wait for the second vibration, roughly 58 seconds later, then press any button to reset the shutoff timer (see below).
6. Draw slowly, 5–10 seconds, like a thick milkshake through a straw. Then step up as the bowl goes (see temperatures).

If yours came from anywhere other than an authorised dealer, run through the counterfeit checks before you register it. Registration at storz-bickel.com takes the warranty from two years to three, and the window is 30 days.

Storage and flying. Keep it upright, out of direct sun and away from radiators. The body won't mind, but sealed cells don't like sitting at 35°C for weeks. If it's going away for a fortnight or more, leave the battery around 50–60%, empty the chamber and brush the screens. For flights, the two 18650 cells add up to roughly 23.8 Wh, well inside the 100 Wh cabin limit. Pack it in hand luggage only, never the hold, with the chamber empty and the device packed so it can't switch itself on.

Loading and Technique

Grind medium, like cracked peppercorn or coarse sea salt. The ceramic chamber is wide and shallow. Grind too fine and the bed compacts, the hot air finds a channel around it, and dust clogs the base screen. Grind too coarse and the middle of each piece never gets heated through. A decent four-piece grinder with teeth that shear rather than tear is all you need. Avoid electric blade grinders, card grinders and pre-ground herb. For sticky, resinous flower, go slightly finer. For dry or older herb, load a touch more and start 5°C lower (our herb prep guide covers the rest).

The knack: wait for the second vibration. At the first buzz, the chamber has reached temperature but the core of the herb bed hasn't. The gap before the second buzz, which is nominally the auto-shutoff warning, lets convection heat soak right through. Press a button to cancel the shutoff, then draw. The difference is real. Bowls finish in 5–8 draws instead of 12, the first hit is dense instead of apologetic, and the spent herb comes out an even mid-brown with no green patches. None of this is required, because the hybrid heater forgives sloppy technique, but it's the gap between the floor and the ceiling.

End of the bowl: when the vapour starts thinning, switch to short 1–2 second cigar-style puffs. They pull more out of a tired bed than long drags do, and it's worth two or three extra hits.

Dosing capsules are the biggest quality-of-life upgrade most owners never bother with. Fill four to eight before you sit down, fill slightly proud, tap to settle and don't press. Drop one in, run the session, then swap it. The chamber stays far cleaner and every dose is pre-measured, which matters if you're dosing medically. Capsules run slightly cooler because of the air gap, so add 2–3°C to your set point. What capsules don't do is keep the cooling unit clean, because that's where the vapour condenses.

Boost and Superbooster: double-tap power for Boost (+15°C) and triple-tap for Superbooster (+30°C total). Either one lasts about 90 seconds and tops out at 210°C. Use Boost for the last draws of a bowl. If you're using Superbooster as a routine move, you're flogging a spent bowl, so reload. I once handed mine to Tom mid-session and told him to boost it. He held the up arrow until the set temperature read 205°C and sat there for the rest of the bowl. Double-tap boosts. Holding up just moves the set point, and nothing warns you. Everyone does this once.

Going through water: the S&B 14mm and 18mm adapters drop the Mighty+ into a standard bubbler or bong. The vapour comes out cooler still and a little closer to glass-path flavour. It's a deliberate 200–205°C home-session move rather than an everyday one.

Temperature Settings: The Best Temps and Timing for the Mighty+

The best temperature for the Mighty+ is 185°C for most sessions. Set 185°C, wait for the second vibration (about a minute after the first), then take slow 5–10 second draws. Step up to 190°C after three or four draws and to 200°C when the flavour fades, then double-tap Boost for the last two draws.

Setting	What you get	When to use it
160–175°C	Bright, grassy, thin vapour. Terpenes only	Tasting a new strain before you work it
175–185°C	Full terpene flavour, light body	Daytime and flavour-first sessions
185–195°C	Deeper, fuller, visibly dense	Most sessions. The sweet spot, so start here
195–210°C	Roasted, heavy, sedating	The end of the bowl and the end of the day
Boost (double-tap, +15°C)	About 90 seconds hotter, then back to your base setting	The last two draws, when the vapour thins
Superbooster (triple-tap, +30°C)	Straight to the 210°C ceiling. Harsh edge, little gain	Rarely. Reload instead

Timing at a glance: about 60 seconds to heat up from cold, then about another minute until the second vibration. After that come 5–8 draws with the knack (10–12 without it) over a 10–15 minute session. Stop when the vapour genuinely thins. The spent herb should be an even mid-brown. Green patches mean channelling (loosen the pack or grind coarser), and black means you sat too hot for too long.

Adjust for the flower. Citrus-forward, limonene-led strains want 175–185°C for the first few draws, because above 190°C the citrus is simply gone. Myrcene-heavy indicas open up at 185–195°C, so start at 180°C and be at 195°C by draw three. Peppery, caryophyllene-rich hybrids are happy sitting in the balanced zone. Dense, greasy flower pulls apart nicely at 195–205°C. Remember that the number on the screen is chamber temperature, and the cooling unit strips a lot of heat out before the vapour reaches you, which is why 200°C feels gentle here. The temperature guide covers the theory, and the strain test above shows what each stage tastes like on two real strains.

Cleaning Schedule and Deep Clean

The cooling unit is where all the work is. Almost everything else on the Mighty+ is maintenance-free. The single highest-return habit is the hot cotton-bud swab from the cleaning section above. Done religiously, it roughly halves how often you need the full teardown.

How often	Job	Time
Daily (every session)	Brush the chamber out while it's warm. Tip the spent herb into a tin	5 seconds
Weekly (every 5–10 sessions)	Warm dry cotton-bud swab of the cooling unit, straight after a session	1 minute
Every 2–4 weeks (15–30 sessions, or when draw resistance climbs)	Full cooling unit teardown and IPA soak (below)	40 minutes, mostly waiting
Every 6–12 months	Replace the screens and O-rings (Wear & Tear set)	2 minutes

The deep clean, step by step:

1. Let everything cool completely, then close the sink plug. I've watched a blue O-ring vanish down a drain.
2. Twist the cooling unit off and separate the two halves by pressing the button nub.
3. Take off the cap lock (the piece with the holographic logo) and set it aside. Don't soak it. The hologram discolours permanently in IPA, so just wipe it with a barely damp bud.
4. Remove the blue O-rings and the screen with the supplied tool. Don't soak the O-rings either. Give them a brief swish and dry them, because long soaks degrade the rubber.
5. Soak both cooling unit halves and the screen in 90%+ isopropyl alcohol for 30 minutes, in a glass jar.
6. Dig out the corners with cotton buds and pipe cleaners. A wooden toothpick handles the stubborn corners of the maze.
7. Rinse in warm water and air-dry for at least an hour. Never reassemble anything damp.
8. Wipe the chamber with an IPA-dampened bud, holding the device upside down so nothing runs into the electronics.
9. Reassemble and run one empty burn at max to drive off any leftover IPA.

Never soak the main body (it isn't sealed), never use boiling water (PEEK copes but the O-rings don't), never use abrasives on the screen or inside the cooling unit, and never use any solvent other than isopropyl alcohol. S&B say other solvents void the warranty. Owning two or three cooling units and rotating them (one in use, one soaking, one drying) turns cleaning from an event that blocks your session into background admin. The owners who say they don't mind the cleaning are, almost without exception, the ones rotating spares. There's more on the chemistry in maintenance chemistry.

Troubleshooting

The Mighty+ has no app, no Bluetooth and no firmware, so there is no software fix for anything. Every fault is mechanical, thermal or a warranty claim, and that keeps this list short.

Problem	Likely cause	Fix
ERR04 on power-on, won't start	Cell imbalance, most common on early batches	Plug directly into a wall socket (not a strip) with a 5V/2.4A+ charger and hold power for 10 seconds. If it comes back, it's a covered warranty fault, so claim it
Thin, wispy vapour	Pack too tight, grind too fine, draws too hard, or you didn't wait for the second vibration	Check all four, in that order. Loosening the pack usually fixes it
Harsh or hot vapour	The cooling unit is overdue a clean, or you started too high	Deep-clean the cooling unit. Step the temperature up instead of opening at 205°C
Burnt or sour taste on a fresh bowl	Old reclaim in the cooling unit tainting fresh vapour, or an over-packed chamber	Deep clean first. This fixes the large majority of burnt-taste reports
Plastic taste on a new unit	Not enough burn-off, or a counterfeit	Two full empty burns at 210°C. If it's still there, run the authenticity checks
Keeps switching off mid-session	The one-minute inactivity timer, working as designed	Press any button between draws. There's no setting to change it
Draw resistance climbing	Clogged base screen or a loaded cooling unit maze	Replace the screen, deep-clean the unit, and grind slightly coarser
Weak draws on a clean device	A tired chamber seal letting air bypass the bowl	Fit a fresh seal ring set
Only 4–5 bowls per charge	Heavy 200°C+ use, or cells over two years old	Run cooler sessions to confirm. Genuinely tired cells are a job for S&B's paid battery service, because the cells are sealed
Charging slowly or not at all	Low-power plug or the supplied cable on a phone brick. Rarely, dead cells	Use a 45W USB-C PD charger. If there's still nothing after 30 minutes on a known-good 5V/2.4A+ charger, it's a warranty claim

Warranty: two years, or three if you register within 30 days. It covers manufacturing defects, electronics, buttons and battery failure under normal use. It doesn't cover drops, water damage, non-IPA solvents, third-party repairs or wear items. Bought from us? Email info@herbvape.co.uk with your order number, serial and a short description (photos or video help) and we'll handle it from the UK, which is usually much quicker than going direct to Germany. ERR04 replacements in particular come back quickly and without argument. The full terms are on our warranty page, and the general why isn't this working walkthrough covers faults shared across all session vapes.

Parts and Accessories That Fit

• USB-C Supercharger, or any decent 45W USB-C PD brick you already own. Without one, you're charging slower than the original barrel-port Mighty did.
• Dosing capsules: a capsule caddy to try them, then a magazine with 8 capsules once you're convinced. Non-negotiable if you're dosing medically.
• A spare cooling unit, or two to rotate. This is the accessory that changes your relationship with the device.
• Wear & Tear set (screens, O-rings, seals) and the seal ring set. Buy them before you lose an O-ring, not after.
• Filling aid, which stops half your grind ending up on the counter, and cleaning brushes, because you'll lose the supplied one.
• Mighty+ case if it travels. It stops accidental power-on in a bag.
• 14mm / 18mm water pipe adapters for home sessions through water.

Skip: the old S&B Herb Mill (it grinds finer than this chamber wants), marketplace "upgraded" screens (unknown metal in your vapour path) and any "replacement battery kit". The cells are sealed, so those kits are warranty-voiding disassembly kits with a nice photo. Our accessories guide covers the general kit.
