30-Second Verdict
The Arizer Solo 3 v2 wins — 9.2 to 8.8 — because it's two vapes in one body: the same glass-path session vape as the Solo 2 MAX, plus an on-demand mode and a faster heat-up. The Solo 2 MAX wins on simplicity, battery runtime and price, and for anyone who only ever vapes in sit-down sessions, it gives you about 90% of the Solo 3 experience for a lot less money. Same glass stems, same Arizer DNA, and one very practical question: will you actually use on-demand?
Arizer Solo 3 v2: 9.2/10
Arizer Solo 2 MAX: 8.8/10
Buy the Solo 3 v2 if:
- You want quick on-demand hits between tasks as well as long evening sessions
- You want the slightly brighter first draws of its hybrid heater
- Faster heat-up matters: about 20 seconds in session mode, about 15 on-demand
- You want the best-scoring portable on this site
Buy the Solo 2 MAX if:
- You only vape in sit-down sessions — load it, sit down, commit
- You want the longest battery of any Arizer portable I've tested: 14–16 bowls
- You want the simplest Arizer there is, with nothing to learn
- You'd rather keep the difference in price for spare stems and a bubbler

The Hook
Every kitchen has a kettle, and a growing number of kitchens have a boiling-water tap.
The kettle is the one you trust. Fill it, flick it on, wait, pour. It's quick enough, it never breaks, and a good one boils a lot of water on one go. You don't think about it. You just make the tea.
The boiling-water tap is the upgrade. Turn the handle and it's already hot — no waiting, no filling, just a quick cup whenever you fancy one. It can still fill a pan for pasta, so it does everything the kettle does and something the kettle can't. It also costs a lot more, and a fair few people who have one admit they mostly use it like a kettle anyway.
The Solo 2 MAX is the kettle. The Solo 3 v2 is the boiling-water tap.
I called the Solo 2 MAX "the Greggs that got a coffee machine" and the Solo 3 v2 "Joy Division becoming New Order" in their own reviews. Both still stand. But the kitchen question is the one you actually face when you're choosing between these two: do you want hot water on demand, or is a quick boil and a proper sit-down all you ever needed?
We stock both at HerbVape.co.uk — details and pricing below.
Vapour Quality
Winner: Solo 3 v2 — 9.5/10 against 9.0/10 — by a margin you'll notice mainly on the first few draws.
Both have the same all-glass vapour path: borosilicate stems, no plastic, no PEEK, nothing added on the way out. That's where the famous Arizer flavour comes from, and both devices have it.
The difference is the heater. The Solo 2 MAX runs the same convection heater that's been in the Solo line since the beginning — its review calls it pure convection. The Solo 3 v2 runs a hybrid — roughly 80% convection and 20% conduction from the stainless oven walls. The Solo 2 MAX review is honest about this: the Solo 3's hybrid heater has a slight edge in terpene expression, but "we're talking marginal gains." On-demand mode is the bigger difference — press, two draws, release — and the Solo 2 MAX can't do it at any setting.
Both are sippers, not rippers. Draw resistance is higher than on S&B devices, and slow, long draws work best — the Solo 2 MAX review calls it "milkshake through a straw", and it applies to both.
The Strain Test, Side by Side
Same jars, same grinder, same weights logged, fresh stems between strains (house rule — a warm stem carries dessert notes into whatever follows). Both devices ran the full two-strain protocol in their reviews.
Jack Herer is where these two sound most alike. The Solo 2 MAX ran fourteen draws over about fourteen minutes, and Jack arrived in the order it was written: pine first, lemon peel behind, pepper later, earth at the end. The glass adds nothing and takes nothing, so a strain with fragile top notes gets a fair hearing. The cost is body — it's a thin, precise vapour. The Solo 3 v2 took 0.13g loose in a standard stem and gave pine on draw one with nothing in front of it, lemon peel just behind, and a cooling menthol edge. At 185°C pepper arrived on draw two while the citrus thinned slowly across three draws rather than dying. Fourteen draws, and at 200°C there was still pepper distinguishable from heat. Same fidelity, slightly more light on the Solo 3. The one place it misbehaves is on-demand: pack Jack's fluffy structure too tight and the first press browns the top layer before you've drawn.
Wedding Cake produced almost identical verdicts. The Solo 2 MAX's was "defined rather than luxurious": it separated vanilla, butter, dough and pepper better than anything else at its money, and handed them over slightly thinner than a cooling-unit device would. The Solo 3 v2 passed the same test outright — four nameable things, not one undifferentiated sweet — and its review admits the rendering is "well-lit and faintly clinical." Both kept the two strains clearly distinct at 200°C: Jack in earth and leather, Wedding Cake in toasted sugar.
The call: if you did these blind, you'd struggle to split them on session-mode flavour. The Solo 3 v2 is a touch brighter at the start of a bowl. The real difference in this category is on-demand, and only one of them has it.
Design & Build
Winner: Solo 3 v2 — 9/10 against 8.5/10.
Both are Arizer cylinders in anodised aluminium, with OLED displays and glass stems that sit snugly in the oven. Both feel built to last years.
The Solo 3 v2 has taken eight months of daily use and several tumbles with no rattles and no error codes. The v1 era was rough — my mate Tom had an Error 5 RMA inside three months — but the v2 has been faultless. It also carries the better warranty on paper: lifetime on the heater, two years on the device, one year on the battery.
The Solo 2 MAX has the better accident story. I tipped around 200ml of Yorkshire Tea over mine at my desk, dried it with kitchen roll, left it for 24 hours and it came back on as if nothing had happened. Please don't test that.
The weak point for both is the glass. I've cracked two Solo 3 stems in eight months and one Solo 2 MAX stem in four. Budget for spares.
Battery & Charging
Winner: Solo 2 MAX, on runtime — both score 9/10.
The Solo 2 MAX does 14–16 bowls at 185–195°C, around 12 run hot at 210°C, and up to 18 on gentle low-temperature sessions. That's the longest battery in the Arizer line and makes every S&B portable look like a sprinter with a pulled hamstring. The Solo 3 v2 does 12–15 bowls at 185–195°C, about 10 run hard at 210°C, and towards 18 on gentle on-demand micro-doses.
The Solo 3 v2 wins the charging race. It supports USB-C PD: Arizer quotes about three hours, but on a decent PD brick I've measured closer to ninety minutes, repeatedly. The Solo 2 MAX takes about three hours from flat.
Both have pass-through charging, so both can live on the desk as a quasi-desktop with the cable plugged in. Neither has a user-swappable battery; if you want that inside the Arizer family, it's the Air MAX.
Ease of Use
Winner: Solo 2 MAX — 9.5/10 against 8.5/10.
The Solo 2 MAX is the easiest Arizer there is. Dip the stem in the grinder, tap, insert, pick a temperature, wait 30 seconds, draw. Its quality-of-life features are genuinely useful: Dark Mode for film nights, an auto-inverting display for when you flip it upside down on a bubbler, and a two-second power-on. No technique required.
The Solo 3 v2's session mode is nearly as simple, and the v2 software fixed most of what was wrong with the original: streamlined menus, custom on-demand presets, degree-precise control across 50–220°C, and the old lock screen can be switched off. On-demand mode has a real learning curve, though. A powerful element will char the top layer if you overfill, and it takes about a week of loose packs with 2–3mm of headroom to get right. Session mode is the fallback the whole time.
Cleaning & Maintenance
Draw on score — both 9.5/10. If you need a winner: Solo 2 MAX, because there's one less way to make a mess.
This is the Arizer party trick, and both do it identically. The herb sits in the glass stem, not the oven, so the stems are the only gunky parts. After months of daily use, both ovens look nearly new. Brush the stem after a session, soak the stems in ISO every 10–15 bowls, and you're done. The honey reclaim in the stems is usable if you're the kind of person who simmers it in milk.
The only difference is that on-demand overpacking on the Solo 3 v2 can leave a charred top layer to scrape out. Session-only means that can't happen on the Solo 2 MAX.
Portability
Winner: Solo 3 v2 — 7/10 against 6.5/10.
On paper, the Solo 2 MAX is the smaller, lighter object: 113mm and 210g against the Solo 3 v2's 130mm and 280g. Both are jacket-pocket devices with a glass stem that needs protecting — a PVC travel tube or a pencil case does the job.
The Solo 3 v2 edges the score because of what it can do once you're out. On-demand mode means a couple of quick draws in the garden or on a walk without committing to a full session. The Solo 2 MAX is session-only: once it's on, you're sitting down. Neither is a pocket vape. If that's your priority, the ArGo or Go SRT are the honest answers.
Value for Money
Winner: Solo 3 v2 — 9/10 against 8.5/10 — even though it costs more.
The Solo 2 MAX is the best-value session vape I've tested at its price: all-glass flavour, marathon battery, pass-through, auto-inverting display and thirty-second cleaning. Its own review puts it as 90% of the Solo 3 v2 for about 60% of the price.
The Solo 3 v2 scores higher on value anyway, because what the extra money buys is a whole second way to vape. It's the best value-per-quality ratio in the £200–300 portable bracket, and its heater warranty is for life.
Which is better value for you depends on one honest question: if you've never wanted an instant hit between tasks, the Solo 3's premium buys something you won't use.

Four categories to the Solo 3 v2, one to the Solo 2 MAX, two level (and I've called those two for the Solo 2 MAX on the details). Both are among the highest-scoring devices on the site. The Solo 3 v2 wins where versatility counts; the Solo 2 MAX wins where simplicity does.
Who Should Buy Which
Buy the Solo 3 v2 if you vape in more than one way. Long sessions in the evening, quick on-demand hits during the day, maybe a micro-dose between work tasks. It's the more capable device, the faster charger and the highest-scoring portable on this site, and the on-demand mode is the reason.
Buy the Solo 2 MAX if every session you've ever had involved sitting down. You want Arizer glass-path flavour, the longest battery in the range, pass-through at your desk and nothing to learn. It's also the better water-pipe partner, thanks to the auto-inverting display.
Already own a Solo 2? The MAX is worth it for USB-C and the extra features. Already own a Solo 3 v2? Don't sidegrade — you'd be giving up on-demand for a bit more battery.
How I Actually Choose
The Solo 3 v2 is about 35% of my total vaping now — most evenings for pain management, and on-demand micro-hits during the working day: press, two draws, release, back to the spreadsheet. Dave's 3D Flow stem lives on it when I'm home.
The Solo 2 MAX gets three or four evenings a week, with the pass-through cable permanently plugged in at my desk. It's what I pick up when I want clean Arizer flavour without deciding anything, and it's my default on the bubbler.
My mate Jake has a Solo 3 and never stops going on about on-demand mode — fair enough, it's brilliant — but his sits on the desk about 80% of the time doing exactly what a Solo 2 MAX would do. When I explained the difference to Sarah — one heats in thirty seconds, the other can do a quick hit instantly — she said, "So it's the boiling-water tap." She's wanted one for years. We don't have one.
The Verdict (The Bookend)
The boiling-water tap is the better appliance. Instant hot water when you want a quick cup, a full pan when you want pasta, and it looks great. The Solo 3 v2 is the better vaporiser: 9.2 against 8.8, the same glass-path flavour, a faster heat-up and charge, and a whole on-demand mode on top.
But most people make most of their tea with the kettle, and there's no shame in that. The Solo 2 MAX is the purest session vape Arizer make: the longest battery, the easiest controls, the same stems, and a lot less money.
If you'll use on-demand, get the tap. If you won't, get the kettle and buy some spare stems with the change.
FAQ
Arizer Solo 3 v2 vs Solo 2 MAX — which should I buy?
The Solo 3 v2 if you want on-demand hits as well as sessions, faster heat-up and the highest score (9.2). The Solo 2 MAX if you only vape in sit-down sessions and want the longer battery, simpler controls and lower price (8.8).
What's the difference between the Solo 3 and Solo 2 MAX?
The Solo 3 v2 has a hybrid heater and on-demand mode and heats in about 20 seconds. The Solo 2 MAX has Arizer's classic convection heater, is session-only and heats in about 30 seconds. Both have all-glass vapour paths, USB-C, pass-through and 50–220°C control.
Is the Solo 3 v2 worth the extra over the Solo 2 MAX?
Yes if you'll use on-demand — you're buying a second way to vape in the same body. If you only ever do sessions, the Solo 2 MAX gets you the same glass-path flavour for much less.
Which has better battery life?
The Solo 2 MAX, with 14–16 bowls per charge against the Solo 3 v2's 12–15. The Solo 3 v2 charges faster on a USB-C PD brick, in about ninety minutes against about three hours.
Do Solo 2 MAX stems fit the Solo 3?
Yes. The Solo 3 v2 shares the Arizer glass ecosystem, so Solo 2 and Air MAX stems carry over. The standard stem is better than the XL pod for even extraction.
Which is better with a water pipe?
Both work well. The Solo 2 MAX has an auto-inverting display that flips when you turn it upside down on a bubbler, which makes it my default water-pipe partner.

Affiliate links and discount codes exist because running a site costs money, not because they influence scores. This comparison reflects eight months of daily use with the Solo 3 v2 and four months with the Solo 2 MAX.
Strains Used: Jack Herer — sativa (Haze × Northern Lights #5 × Shiva Skunk), ~20% THC, terpinolene/caryophyllene/pinene-dominant, pine-citrus-pepper profile with fragile top notes. Wedding Cake — indica-leaning hybrid (Triangle Kush × Animal Mints, via Triangle Mints #23), ~24% THC, caryophyllene/limonene/myrcene-dominant, vanilla-cream-dough dessert profile over peppery earth. Same two strains, same jars, across every vaporiser reviewed on this site — the strain is the control, the device is the variable. Strain effects vary by individual, batch and consumption method.
