30-Second Verdict
Both of these devices score 8.7 on this site, and neither score is a typo. The Mighty+ gets there by doing one thing perfectly with zero input from you. The Legacy Pro 2 gets there by doing everything reasonably well and rewarding you for learning it — with a removable battery, an on-demand mode, and a good chunk of money still in your pocket. I said it in the Mighty+ review and it's the whole article in one line: two genuinely different routes to the same standard. The honest truth: if you have to ask which one to buy, buy the Mighty+.
Mighty+: 8.7/10
Legacy Pro 2: 8.7/10
Buy the Legacy Pro 2 if:
- You enjoy dialling in pack, draw and temperature — and want to be rewarded for it
- A removable 18650 and a lifetime warranty matter more to you than zero learning curve
- You want session AND on-demand in one pocketable body
- The price gap is real money, and you'd rather keep it
Buy the Mighty+ if:
- You want to press a button and vape, forever, without thinking
- You're a first-timer, or buying for someone who is
- Thorough, consistent extraction matters more than feature count
- You'd rather have twenty years of S&B reputation than a spec sheet

The Hook
I work in IT, so let me put this in the terms my day job forces on me.
On my desk at home there's a mechanical keyboard. Hot-swappable switches, lubed stabilisers, a keycap set that took six weeks to arrive from a group buy. It sounds like rain on a tin roof and typing on it is a small daily pleasure. It also took me three evenings to build, one firmware flash that bricked it temporarily, and a level of ongoing fiddling that no reasonable person would sign up for.
At the office, there's a Dell keyboard. It came in the box with the machine. Nobody chose it. Nobody has ever thought about it. It has typed millions of words without a single one of them being interrupted by the keyboard itself. It will outlive the company.
The Legacy Pro 2 is the mechanical keyboard. The Mighty+ is the office Dell.
Here's the uncomfortable bit for the enthusiasts: the Dell types the same words. When I reviewed the Mighty+ I called it the Land Rover Defender of vaporisers, and I called the Legacy Pro 2 the Sage Barista Express — an appliance and an instrument. Both reviews landed on 8.7, and I've had emails asking whether that's a cop-out. It isn't. It's the most honest pair of numbers on the site, because these two devices arrive at the same quality of evening from completely opposite directions. One asks nothing of you. One asks quite a lot, and pays you back with range, flexibility and a lower price.
The question this article answers isn't "which is better." It's "which one are you."
We stock both at HerbVape.co.uk — details and pricing below.
Vapour Quality
Both reviews scored vapour at 9/10, and both meant it — but the nines describe different shapes.
The Mighty+ nine is a flat line. Every bowl, every temperature, every day: smooth, cool, consistent vapour with the cooling unit doing heroic work and zero technique required. It's a sipper — 5–12 draws over 10–15 minutes — and it shows up identically whether it's your first bowl or your thousandth. What it doesn't do is peaks. On-demand devices extract harder, the Venty moves more air, and the same rounding-off that makes it smooth also files the sharpest edges off delicate terps.
The Legacy Pro 2 nine is a mountain range. The opening draws at 195°C are properly dense and properly flavourful — denser than the Crafty+, right in the Mighty+'s conversation at the top of the bowl, and arriving off a fifteen-second heat-up instead of sixty. But it's draw-dependent. Pack it tight or pull hard and the output collapses into warm nothing. The ceiling is high, the floor is embarrassing, and your technique decides which one you're standing on.
Winner: a genuine tie on quality, Mighty+ on consistency, Legacy Pro 2 on peak-for-effort. If you want the best possible draw, learn the AirVape. If you want the same good draw every time, the Mighty+ has never once failed to deliver it.
The Strain Test, Side by Side
Same two jars, same grinder, chamber and airpath cleaned between strains — the strain is the control, so for once the comparison is genuinely direct. The Legacy Pro 2 ran its ladder at 180/192/203°C; the Mighty+ ran its at 180/190/200°C.
Jack Herer
This strain is where the two philosophies stop being abstract.
At the bottom of the ladder, both devices held Jack's fragile top end to about draw four — but they held different versions of it. The Legacy Pro 2, packed deliberately loose in a dosing cap, gave pine clean enough to place with lemon peel behind it, slightly rounded and warm because the pre-heated chamber takes the needle-point off. The Mighty+ gave warm pine rather than fresh pine — the chamber walls and that oversized cooling unit soften it before it reaches you. Neither is the needle-sharp convection version; the AirVape's is marginally the brighter of the two, and the S&B's is comfortably the smoother.
The difference is what it cost to get there. The Mighty+ result required nothing. 0.18g, loose, cold load, done — and the review's verdict was that all twelve draws were the same twelve draws it would have given the previous Tuesday. The Legacy Pro 2 result required a loose no-tamp pack, a slow draw, and — by the mid stage — a gentle re-tamp to bring the density back when the pull stiffened. Its own review admitted at least half the result was Dennis's rather than the machine's. Pack it the way most people will out of the box and Jack is warm green nothing by draw three.
Mid-temp, both devices delivered properly defined black pepper — 192°C on the AirVape, 190°C on the S&B — and at the top both did the correct Jack collapse into earth and toast, the Mighty+ going to leather and light fuel with no scorch, the AirVape a touch drier about it, with an evenly browned ABV proving the convection was doing the work.
On Jack: Mighty+ for anyone who wants the result guaranteed; Legacy Pro 2 for anyone who wants the ceiling and will do the reps.
Wedding Cake
And here they converge, because Wedding Cake flatters everything.
Both devices separated the dessert profile properly. The Mighty+ at 190°C put vanilla, butter, warm baked cake and black pepper on the table as four distinct items — its review called it the cooling unit's finest hour, and it's the bowl that had Sarah walking through the kitchen asking if I'd been baking. The Legacy Pro 2 at 192°C did butter, plainly, with warm dough behind it and pepper emerging without stepping on the sweetness — eleven draws with no re-tamp, no thinking, no negotiation with the airflow. The airflow sensitivity that dogged Jack barely showed up, because the denser bud structure channels less. That's the device relaxing.
The texture split is the honest difference: the S&B's vapour is plusher — that fluffy, hydrating character the cooling unit buys you — where the AirVape reads slightly drier, most obviously at the top of the ladder where its 203°C stage tipped towards burnt sugar a shade quicker than the Mighty+'s composed 200°C finish.
Both are flavour devices by the site's own test — both kept two plants tasting like two plants into the final stage. The Mighty+ verdict was "a flavour device with all the corners filed off." The Legacy Pro 2's was a delivery device that can do genuine flavour — for you on Wedding Cake, by you on Jack. On this pairing, that asymmetry is the entire comparison.
Design & Build
Cork wrap, gold-plated stainless chamber, glass airpath and ceramic mouthpiece versus medical-grade PEEK plastic that looks like Fisher-Price and survives being knocked off the kitchen counter mid-tea-round. The Legacy Pro 2 is the nicer object — genuinely premium in the hand at ~232g, warm to the touch in a way aluminium isn't. The Mighty+ is the tougher one — two years of daily use on mine and the only wear is cosmetic discolouration on the chamber rim.
Then there's the loading. The Mighty+ cooling unit clicks on with a satisfying snap. The Legacy Pro 2 has the clamshell — flip, load, click, and watch AVB stick to the underside of the lid every single time. Sarah's verdict on it from the original review stands unimproved: "That's a stupid lid." The dosing caps rescue it completely, but you shouldn't need rescuing at any price. Note also the QC asterisk: some early Legacy Pro 2 units had cork-veneer bubbling at the corners (warranty sorts it); the Mighty+ has Dave's error-code lottery on its record — five units in two years, every one replaced inside a week.
Winner: Legacy Pro 2 on materials and looks, Mighty+ on take-anywhere-drop-anything build. Scores agree: 8.5 vs 9.
Battery & Charging
This one isn't close, and it's not about the numbers.
On raw numbers they're neighbours: 5–7 bowls per charge for the Legacy Pro 2, 6–8 for the Mighty+. The Mighty+ charges faster if — and it's a real if — you buy the S&B Supercharger separately: ~80% in 40 minutes, versus the AirVape's leisurely three hours over USB-C. Both do pass-through, the Mighty+'s only nominally.
But the Legacy Pro 2's 18650 comes out. A spare cell and a decent external charger turn it into an all-day device, and — the bit that matters at year three — into a device that never becomes a paperweight. The Mighty+'s sealed pair of 18650s puts you on a timer from day one; when they fade, it's an RMA or a warranty-voiding DIY job. For medical users who depend on the thing daily, that's not a spec-sheet difference, it's a reliability difference.
Winner: Legacy Pro 2, and the removable cell is most of the reason its Battery score (8.5) beats the Mighty+'s (8).
Ease of Use
The Mighty+'s entire manual: turn it on, wait a minute, draw. Two buttons. No technique, no learning curve, no way to get it wrong. It's the vape I hand to first-timers and the one I'd give my mum for her arthritis.
The Legacy Pro 2's interface is nearly as simple — three buttons, OLED, 1°C steps from 100–240°C — but the operating isn't. The clamshell loads slower than anything, the on-demand mode is hold-to-heat with a damped response, and the airflow sensitivity means your draw style is a live variable. Three sessions and you've learned it. But that's three sessions the Mighty+ never asks for.
Winner: Mighty+ (9 vs 8), by exactly the margin its target market cares about. The counterpoint: the AirVape's learning curve buys you an on-demand mode, a 140°C-wider temperature range and single-degree control, none of which the Mighty+ offers at any price.
Cleaning & Maintenance
The Mighty+'s one genuine weakness. The cooling unit is a gunk magnet — a sticky brown maze needing a full teardown every 20–30 bowls, and it's where I lost an O-ring down the sink drain and stood watching it go like a very small, very expensive rubber band. Dosing capsules don't save you: the CU gunks up regardless, because that's where vapour condenses. It scored a 5, and it earned it.
The Legacy Pro 2, run capsule-led, is a five-minute weekly job: dump the caps, cotton-bud the chamber, magnetic screen out for an ISO dip. Without caps it's 12–15 minutes and fiddlier — small parts, a gasket that collects herb — but the V2's magnetic screens killed the V1's carpet-fishing misery.
Winner: Legacy Pro 2, comfortably (8.5 vs 5). If cleaning tolerance is your deciding factor, this section just decided it.
Portability
Neither is a stealth device, but one of them at least fits in jeans. The Legacy Pro 2's deck-of-cards footprint (119 × 52 × 21mm) is pocketable-but-noticeable; the Mighty+ (140 × 84 × 30mm) is a jacket-pocket brick with zero pretence otherwise — Sarah named it and the name stuck. The AirVape's cap workflow is what elevates it: pre-load five in a tin and you never open the clamshell in public. That's how it did a six-hour Sunday at Parklife without a single mid-set reload disaster, which is a sentence the Mighty+ will never appear in.
Winner: Legacy Pro 2 (8 vs 6.5), and it isn't close.
Value for Money
Both reviews scored value at 8, which looks like a dodge until you unpack it. The Legacy Pro 2 is the widest feature spread in its bracket — hybrid heating, removable cell, dual modes, caps, lifetime warranty — for noticeably less money. The Mighty+ is a premium's worth of accumulated trust: twenty years of S&B, mature accessories, resale value, and a device four of my mates bought after trying mine.
A real price gap separates them. That's a spare 18650, a charger, a grinder and most of a smell-proof case — the entire AirVape ecosystem funded by the price gap. Against that: the Mighty+ is the safe money, and "safe" is precisely what a lot of people are buying at this price.
Winner: Legacy Pro 2 on arithmetic, Mighty+ on certainty.

Four categories to the AirVape, two to the S&B, one dead heat — and the same overall. The Mighty+'s wins are in the categories beginners feel; the Legacy Pro 2's are in the ones enthusiasts feel.
Who Should Buy Which
If you've never owned a serious vaporiser, buy the Mighty+ and stop reading. Everything about it — the two-button interface, the forgiving pack, the vibration when it's ready, the twenty-year reputation — is engineered for the person who wants vapour, not a hobby. It's the device I've handed to more first-timers than I can count, and the reason I give the same slow-draws speech every time.
If you're the person who already owns a decent grinder, weighs doses, and reads temperature guides for pleasure — the Legacy Pro 2 was built for you, and it'll cost you less. You get the removable battery the Mighty+ has always refused you, an on-demand mode for between-meetings top-ups, and a device that genuinely improves as you learn it. You also get a clamshell lid and a three-session apprenticeship, and you'll enjoy both, because you're that person.
The trap buyer is the one in the middle: tempted by the AirVape's spec sheet but honest enough to know they'll pack it tight, pull hard, and conclude it's broken. Dave — a Mighty+ man to his bones — proved the point in my kitchen. He loaded the Legacy Pro 2 exactly the way he loads his Mighty+, drew on it like he was drinking a milkshake, got warm air, and handed it back with a flat "It's broken." It wasn't. It just wasn't a Mighty+. That's the entire buying decision in one anecdote.
How I Actually Choose
The Mighty+ lives on the kitchen counter and has done for two years — roughly 30% of my total usage, the 8pm pain-management sessions, the no-decisions-just-vapour evenings. The Legacy Pro 2 has a rotation slot at three or four sessions a week: going-out days, weekend trips, and any evening I'm in a tinkering mood and want to dial something in rather than have it handed to me.
The honest pattern: when I'm tired, hurting, or can't be bothered, I reach for the Mighty+ every single time. When I've got the energy to enjoy the process, the AirVape rewards it. Same standard, different moods — which is what two 8.7s look like from the inside.
The Verdict (The Bookend)
The office Dell has typed more words than the mechanical keyboard ever will, and it has never once been the reason the words stopped. That's the Mighty+: the default that just works, the one you recommend to everyone precisely because it requires nothing of them.
But the mechanical keyboard is the one I look forward to sitting down at. The Legacy Pro 2 does more things, costs less, cleans easier, travels better, and will still be running on its fourth battery when sealed devices are landfill. It just asks you to care — and the Mighty+'s entire genius is that it doesn't.
Same score. Same standard. Two genuinely different routes there. Buy the one that matches your temperament, not your wishlist — and if you're not sure which temperament you have, that itself is the answer: Mighty+.
FAQ
Legacy Pro 2 vs Mighty+ — which should I buy?
If you want zero learning curve and don't mind cleaning a cooling unit, the Mighty+. If you enjoy technique, want a removable battery and on-demand mode, and would rather keep the difference, the Legacy Pro 2. Both score 8.7 — the choice is temperament, not quality.
Is the Legacy Pro 2 a "Mighty killer"?
No, and AirVape have stopped pretending. On vapour they're a genuine tie at 9 apiece; the Mighty+ extracts more thoroughly with zero technique, the Legacy Pro 2 offers more features for less money. Different vapes for different brains.
Which is easier to clean?
The Legacy Pro 2, by a distance. Capsule-led, it's five minutes a week. The Mighty+ cooling unit needs a full teardown every 20–30 bowls, and it's the reason the Mighty+ scores 5/10 for cleaning against the AirVape's 8.5.
Which has the better battery?
The Mighty+ manages 6–8 bowls to the AirVape's 5–7, and fast-charges with the Supercharger. But the Legacy Pro 2's 18650 is removable — a spare cell makes it an all-day device, and it'll never become a paperweight when the cell ages. Long-term, that wins.
Can either be used with a water piece?
Neither is built for it. The Mighty+ has third-party adapters and the Legacy Pro 2 can be adapted similarly, but if bong use is a priority, look at a device designed for it — the VonG X exists for exactly that.
Which holds flavour better on delicate strains?
Honours even, with caveats. The Legacy Pro 2 can go slightly brighter on Jack Herer — if you pack loose and draw slow. The Mighty+ gives a softer, rounder version of the same notes with no technique at all. Both kept the two benchmark strains distinct to the top of their ladders.
What about warranties?
Legacy Pro 2: lifetime, if you register within 30 days — do it the day the box arrives. Mighty+: 2 years, 3 with registration inside 4 weeks, backed by S&B's genuinely fast replacement service.
