30-Second Verdict
The Wolkenkraft Äris wins — 7.8 to 7.5 — and it costs £54 more for vapour that scored exactly the same. Both are pure convection through a titanium chamber into a glass mouthpiece. Both come out of the same Fenix development family. The vapour category is a dead heat. What £54 actually buys you is certainty about what that vapour has passed through, plus two extra years of warranty and a fan that announces your session to the entire ground floor.
Wolkenkraft Äris: 7.8/10 | £129.00 Smono No.3: 7.5/10 | £75.00
Buy the Wolkenkraft Äris if: - You think about residue — what's behind the screen, what's in the bend you can't see - You rotate strains and want each one delivered without the last one's ghost in it - You want a 5-year warranty, pass-through charging and a 100°C floor for CBD-dominant terpenes - The noise genuinely doesn't bother you, and you've been honest with yourself about that
Buy the Smono No.3 if: - You want the same vapour path philosophy for £54 less and don't mind a pipe cleaner - You use it in quiet rooms, near sleeping people, or anywhere the word "discreet" applies - Degree-by-degree control, a forgiving convection chamber and a bowl you can't overpack are the whole brief - You'd rather spend the £54 on flower, a grinder and a smell-proof case

The Hook
There are two ways to get something properly clean, and the difference isn't really about the result. It's about who does the worrying.
The first is the dry cleaner. You hand the thing over the counter, a ticket gets stapled to it, and somewhere in the back a machine hisses and thumps through a process you don't fully understand and can't watch. Days later it comes back on a wire hanger under a plastic sheath, and it is clean — clean in a way you couldn't have achieved yourself, clean in the seams, clean where the fabric folds. It costs more than you'd like. There is a permanent low industrial noise coming from behind that counter that everyone in the queue has agreed not to mention.
The second is the launderette. Plastic chairs, strip lighting, a change machine that eats fivers. You do the work: you sort it, you load it, you sit there for forty minutes with your phone at 12%. It costs almost nothing, it gets the job done, and nobody has ever walked out of a launderette feeling posh. But your clothes are clean, and you know exactly what happened to them, because you watched it happen through a round window.
The Wolkenkraft Äris is the dry cleaner. The Smono No.3 is the launderette. Same fundamental job. Completely different relationship with the word "clean."
I called the Aris the Dyson fan of vaporisers in its review, and the Smono No.3 got the Aeropress treatment in its own. Set both aside. What matters for this pairing is that these two devices are, functionally, siblings — pure convection, titanium chamber, glass at your lips, both rebadges off the Fenix platform (the Aris from the Fenix Pro, the Smono from the Fenix Mini). Their vapour quality scores are identical. Their portability scores are identical. This is not a comparison of how they vape. It is a comparison of what happens afterwards, and what you're willing to pay for the answer.
One of them scores higher. It's the dry cleaner. The launderette is going to make you think about it, though.
We stock both at HerbVape.co.uk — details and pricing below.
Vapour Quality
Both reviews scored this 8.0/10, and I want to be blunt about why: they are doing the same thing with the same materials.
Pure convection means hot air pulled through the herb without touching a hot wall. Titanium means the chamber contributes nothing — no stainless tang, no ceramic colouring. Glass means the last few centimetres before your lips add nothing either. Both devices land the same trick, and both reviews used almost the same words for it: terps arrive individually, limonene first, then myrcene, then the background notes that conduction smears into one flavour. Neither needs stirring. Neither needs technique beyond a sensible grind and a gentle pack.
Where they separate is the ceiling. The Aris review found that above 205°C the convection holds density where budget competitors give up, and named the Smono No.3 specifically as the device that thins out above 210°C. The Smono review said the same thing from the other side — a warning box, not a footnote: stay below 210°C and it's exceptional, push past and you get warm air and a lesson about £75. The Aris's 2600mAh cell and dedicated fan motor sustain heat output that the Smono's 1600mAh simply cannot.
The other separation is the floor. The Aris starts at 100°C; the Smono starts at 160°C. That sixty-degree difference is irrelevant to most people and quietly enormous to a few — it's the range where CBD-dominant terpene work happens, and if you're doing that, the Smono cannot follow you down there.
Draws inside 175–200°C: genuine draw, and I've tried to find daylight between them. Above 205°C or below 160°C: Aris, uncontested. In the middle — which is where I actually live — you would not pick these apart blind, and the £54 is not buying you flavour.
The Strain Test, Side by Side
Plain statement first, because the alternative is inventing data: neither of these reviews ran the site's Jack Herer and Wedding Cake control. Both were tested on their own pairs — the Aris on Gelonade and Curaleaf Gorilla Girl T24, the Smono No.3 on Apple Fritter and Noidecs T20 Lemon Skunk. So there is no like-for-like lap chart here, and I'm not going to pretend one exists. What I can do honestly is line the two up by terpene family, because both reviews happened to test one bright limonene-forward strain and one caryophyllene-dominant dessert strain each. That's a comparison. It just isn't the control.
The bright citrus lane — Gelonade (Aris) against Lemon Skunk (Smono No.3). Both are limonene-dominant with terpinolene underneath, and both reviews reached independently for the same unusual word: shimmer. The Aris at 170°C gave sharp, bright, unmistakable citrus zest with the terpinolene adding an incense-like depth beneath it, three draws of it, the 0.15g bowl concentrating the complexity rather than spreading it thin. The Smono at 170°C gave lemon zest so sharp its review called it almost citrus peel, with the terpinolene shimmering underneath in exactly the same register — and then said the thing that matters most in this whole comparison: that limonene was sharper and more distinct than through any conduction device tested at any price. Two reviews, two different jars, the same finding. That is what a shared vapour path does. The titanium doesn't know what it cost.
The dessert lane — Gorilla Girl (Aris) against Apple Fritter (Smono No.3). Here the strains diverge more, so read this as terpene behaviour rather than a race. Both are caryophyllene-dominant with a sweet baked note on top. The Aris took Gorilla Girl to a full medical extraction at 190°C — cookie sweetness from the GSC side, humulene depth, dense resinous vapour — and its review flagged what the strain was really testing: resin building visibly on the chamber walls, a deliberate no-capsule direct load chosen to see what the ECA system could recover. The Smono took Apple Fritter through apple sweetness at 175°C into vanilla cream at 185°C and cinnamon at 200°C, and its review's observation was about the mechanism rather than the residue: each draw was slightly different, because convection passes through the flower differently each time and reveals layers. The Aris's dessert strain was chosen to make a mess. The Smono's was chosen to be delicious. That difference in intent tells you what each review thought its device was for.
The call: on flavour, this is a genuine draw and both reviews' own numbers say so. The Aris's advantage isn't a better first bowl — it's the hundredth bowl. When you've run a resinous, pungent strain and then want a delicate one, the Aris hands you the delicate one clean and the Smono hands it to you with whatever the pipe cleaner missed. Both of these taste the same. Only one of them will definitely still taste the same in year three.
Design & Build
Winner: Wolkenkraft Äris. 8.0/10 versus 6.0/10, and it's the widest honest gap on the card.
The Aris is 133 grams of solid, compact German-built device with a gold-plated mouthpiece ring, a crisp OLED display and — the actual engineering achievement — an airpath designed from the outset to come apart. Its review's phrase for the gold ring was "engineering theatre": unnecessary, premium, the detail that tells you somebody considered this. The Fenix Pro heritage is stated openly and adds credibility rather than doubt.
The Smono No.3 is plastic. Not "soft-touch composite" — budget plastic that flexes if you squeeze it and creaks if you grip it while drawing. Its review set it next to a DaVinci IQ3 and called the material gap visible from across the room, and then made the only argument that matters: the exterior is B&M Bargains and the interior is John Lewis. The chamber that touches your herb is the same titanium the Aris uses. The mouthpiece is real borosilicate. You are paying £75 for a premium vapour path in a shell that has given up on impressing you.
The Aris is the better object. The Smono is the better trick. Six out of ten for a device whose only genuine build failing is that it looks like what it costs seems about right, and so does eight for one that doesn't.
Battery & Charging
Winner: Wolkenkraft Äris — comfortably. 7.0/10 versus 5.0/10.
The Aris does 6–8 sessions on a 2600mAh cell, charges over USB-C in about eighty minutes, and supports pass-through, which for a device that mostly lives at home is worth more than the raw capacity. A moderate user gets an evening without thinking about it.
The Smono does 5–6 sessions on 1600mAh, takes roughly 120 minutes to charge, and pass-through is not recommended. Its own review called this the price of admission and didn't flinch: a heavy user drains it before lunch, a moderate user gets an evening, a microdoser gets a day. Both batteries are sealed, so both degrade permanently — but the Smono starts from less and its 3-year warranty explicitly doesn't cover capacity loss, because degradation is wear, not defect.
Neither of these is an all-day device. The Aris is an all-evening device. The Smono is an all-evening device if the evening isn't ambitious.
Ease of Use
Winner: Smono No.3. 8.0/10 versus 7.0/10 — the Smono's only outright category win besides value, and it earns it by doing less.
The Smono's interface is plus, minus, a small display, and nothing else. No app, no capsules to manage, no modes. The 0.2g bowl is so small you almost can't overpack it — drop in a medium grind, don't compress, draw. Its review's Mum test was a straight pass, and Mum's verdict was "Plus and minus? Even I can do that, love." The convection is genuinely forgiving.
The Aris has more: OLED, 1°C precision, haptic confirmation when temperature is reached, a stealth mode, an adjustable 3–7 minute session timer, and a dosing capsule system. Some of that is useful. Some of it is features for a device that works best when you set a temperature and draw. And the 0.15g chamber is less forgiving than the Smono's — overpack it and you strangle the airflow that makes convection work at all.
Then there's the noise, which is where the dry cleaner's back room comes into it. The Aris's convection fan is audible from three metres in a quiet room, roughly the volume of an electric shaver, and it is the single most consistent complaint about the device anywhere. Its own review's Mum test came back MIXED for exactly this reason — she cleaned it happily and then asked what the noise was. Stealth mode dims the display, which its review correctly called ironic. The Smono makes no noise worth reporting.
Living room: both fine. Spare room at 1am with someone asleep next door: only one of these.
Cleaning & Maintenance
Winner: Wolkenkraft Äris, 10/10 versus 7.0/10 — and this category is the entire comparison.
The Aris's ECA (Easy Care Airpath) system is the only 10 in this pairing and one of the very few full marks anywhere on the site. Every component of the airpath separates. Every surface can be wiped, soaked, brushed and — this is the part that matters — looked at. There is nowhere for residue to hide. Its review's summary of the difference is the best line either of these articles produced: with normal cleaning you believe it's clean; with ECA you know it's clean. After the deliberately resinous Gorilla Girl session, the whole coated airpath came back to factory-fresh in under two minutes.
The Smono is not badly served, and 7 out of 10 isn't a criticism. The titanium chamber brushes clean in seconds and resists staining better than steel or ceramic; the glass mouthpiece soaks in ISO and comes out spotless; the small bowl means less resin per session. But the internal channel is not accessible. You run a pipe cleaner through it weekly and compressed air when you remember, and you finish the job at the level of confidence the launderette gives you: it's clean, probably, and you're not going to check.
The Aris's one maintenance annoyance is real and worth stating: the mouthpiece screen clogs after about five days of regular use, which is odd for a device that solved the harder problem so completely.
Sarah walked past the kitchen while eleven pieces of Aris were drying on a tea towel next to the intact Smono and asked, with real doubt, "Is that all one thing?" I said it was. She looked at the Smono, then at the tea towel, then back at me, and said, "It'd better go back together." It did. That is, in fairness, the reasonable question about ECA, and the answer is that it goes back together every time and always has.
Portability
Draw. 7.0/10 apiece, and the tie is deserved.
The Aris is 133g and compact; the Smono is roughly 140g and compact. Both go in a jacket pocket. Neither goes in jeans. Both have glass at the mouthpiece end, so both want a case rather than a loose pocket — the Smono review's line about treating the glass like a wine glass applies equally to the Aris's pyrex.
The tiebreaker isn't size, it's sound. The Aris is visually discreet and audibly not: park bench fine, library absolutely not. The Smono is the one that travels quietly. If "portable" means "leaves the house and doesn't announce itself," the Smono wins a category the scores call level — but the Smono's 1600mAh battery then takes that win straight back off it, because the quiet device is the one that dies first. They cancel. Seven each.
Value for Money
Winner: Smono No.3. 9.0/10 versus 8.0/10, with the £54 price gap running the same direction.
The Smono No.3's review called it the best value in portable vaping and I've not found the argument against it. Pure convection, titanium chamber, glass mouthpiece, degree-by-degree control, USB-C and a 3-year warranty for £75 is a spec list that embarrasses devices at £109 and £119. Two compromises — the battery and the shell — and everything else punching two weight classes up.
The Aris at £129 makes a different and slower argument, and its review made it properly: ECA isn't cleaning, it's prevention. A vaporiser you can fully clean outlasts one you can't, and over a 5-year warranty period the per-year cost lands under £30 with the airpath still factory-clean at the end. That's genuinely good value. It's just value you collect in year four, whereas the Smono hands you its value at the till.
The dry cleaner charges you £54 to be certain. The launderette charges you nothing extra and asks you to believe.

Read the table honestly and the shape is clear: the Aris wins three, the Smono wins two, two are drawn — and the Aris's margin comes almost entirely from one category where it scored a perfect ten. Take cleaning out of the arithmetic and these two devices are level, with the cheaper one ahead on the categories a first-week owner notices. The 0.3 between them is, near enough, the ECA system expressed as a number.
Who Should Buy Which
Buy the Wolkenkraft Äris if you're the person who cleans a vaporiser and still isn't sure it's clean. That's not a niche — it's most medical users rotating strains for different symptoms, everyone who's ever pulled a cooling unit apart and found something they didn't want to see, and anyone whose relationship with their kit runs to years rather than months. You want pass-through for home sessions, the 100°C floor for terpene-specific work, a 5-year warranty that removes replacement anxiety, and a device where the maintenance question has an actual answer. You have also, please, been honest with yourself about the fan. Everyone who ends up unhappy with an Aris is unhappy about the noise, and every single one of them was told.
Buy the Smono No.3 if you want the vapour and not the ceremony. It is the best flavour-per-pound device on this site and the vapour category scores prove it isn't a compromise where it counts. It's the right answer for anyone stepping up from a conduction pen and wanting to hear what convection actually does, for microdosers whose 0.2g bowl is a whole session anyway, for people who vape in quiet houses, and for anyone whose budget is the reason they're reading this. Its review's own best evidence is that a committed vape snob tried it once and ordered one the next day.
The wrong buyer for the Aris is someone in a shared flat with thin walls, or anyone whose actual complaint about their current device is capacity rather than cleanliness — 0.15g is smaller than what the Smono gives you. The wrong buyer for the Smono is the strain-rotating medical user who needs each prescription delivered in isolation. That is precisely the job ECA was built for and precisely the job a pipe cleaner cannot promise.
How I Actually Choose
The rotation data doesn't lie, and I keep rotation data, because ADHD.
The Aris is my clean-room device. When a delicate jar arrives and I want to taste absolutely nothing except the flower, it's the Aris, at 180°C, kitchen door shut — that door being the compromise Sarah and I reached and which its review already documented. Roughly two evenings a week, more when I'm alternating strains and want each one uncontaminated by the last.
The Smono No.3 is the one that leaves the house and the one I hand to people. It goes in the jacket, it doesn't announce itself, and if I lose it I've lost £75 rather than £129. It's also the device I lend, which is the quietest compliment I can pay a vaporiser: I have never once worried about what someone else's technique would do to it, because there isn't any technique to get wrong. Both its review and the Aris's have a Dave story attached and I'm not retelling either — but the short version is that the plastic one converted a sceptic and the titanium one sold itself on a single word.
Here's the tell, though. When I go away for a weekend, I take the Smono. When I come back, the first thing I do is not reach for the Aris — it's clean the Smono, properly, for longer than it needs, with the vague dissatisfaction of a man running a pipe cleaner through a channel he cannot see. That's the £54, right there. Not in the vapour. In the ten minutes afterwards where one device settles the question and the other one leaves it open.
The Verdict (The Bookend)
Nobody walks out of a launderette with their clothes on a wire hanger under a plastic sheath. And nobody has ever handed a duvet cover across a dry cleaner's counter without wincing at the price.
The Aris wins, 7.8 to 7.5, and the win is honest but narrow, and it is bought almost entirely with one perfect score. What £54 gets you is not better vapour — the reviews scored that dead level and I couldn't separate them in six months of use. It gets you a 5-year warranty, an extra thousand milliamp-hours, a sixty-degree lower temperature floor, a device that feels like it cost what it cost, and the only airpath in portable vaping you can take apart, inspect and know. And it costs you a fan that sounds like an electric shaver, which is a real price and not a footnote.
The Smono No.3 keeps its own crown and it should be said plainly: the same titanium, the same convection, the same glass at your lips, for seventy-five quid, in a shell that has stopped trying to convince you. If that sentence is why you're here, no score table should talk you out of it, and this one isn't trying to.
Buy the dry cleaner if you think about what's in the seams. Buy the launderette if you just want it clean by Tuesday. Both of them get it clean. Only one of them shows you.
Just one more bowl.
FAQ
Wolkenkraft Äris vs Smono No.3 — which should I buy? The Aris if cleanliness of the airpath is something you actively think about, and you can live with the fan noise: it scores higher (7.8 vs 7.5), has a 5-year warranty, a bigger battery and pass-through charging. The Smono No.3 if you want the same pure-convection titanium vapour for £54 less (£75 vs £129.00) and don't mind doing the maintenance yourself with a pipe cleaner.
Is the Aris's vapour actually better for £54 more? No, and I'd rather say so. Both reviews scored vapour quality identically. The Aris holds density better above 205°C and reaches down to 100°C where the Smono stops at 160°C, but between 175 and 200°C — where nearly everyone lives — they are the same device wearing different shells. The £54 buys cleaning, warranty, battery and build.
How loud is the Aris, really? About an electric shaver, audible from three metres in a quiet room. It's the device's single most consistent criticism and the reason its Mum test came back mixed. If you vape with music on you'll forget it. If you vape in silence, or near someone sleeping, it rules the device out. The Smono is quiet.
Which is easier to clean? The Aris, by the widest margin in this comparison: 10/10 against 7/10. Its ECA system separates the entire airpath so every surface can be wiped and inspected — a resin-heavy session cleaned back to factory-fresh in under two minutes. The Smono's chamber and glass are easy, but the internal channel is pipe-cleaner-and-hope territory. Note the Aris's one flaw: its mouthpiece screen clogs after roughly five days of regular use.
Are they the same device underneath? Closely related, not identical. The Aris is a Wolkenkraft-badged Fenix Pro; the Smono No.3 is a Smono-badged Fenix Mini. Same development family, openly stated in both reviews, which is why the vapour paths behave so similarly. The Aris is the larger, better-equipped branch of the family — bigger battery, wider temperature range, and the ECA airpath the Mini platform doesn't have.
Which battery lasts longer? The Aris: 6–8 sessions from 2600mAh, roughly eighty minutes to charge, with pass-through so it can run plugged in. The Smono manages 5–6 from 1600mAh, takes about 120 minutes, and pass-through isn't recommended. Both are sealed, so both degrade permanently over 12–18 months of daily use — the Aris just starts from more.
Is the small bowl a problem on either? On the Aris, sometimes — 0.15g is microdose territory and a moderate evening is two loads. The Smono's 0.2g is marginally more generous and also close to unoverpackable, which is part of why it wins ease of use. If bowl size is your actual complaint about your current vaporiser, neither of these is your answer, and both reviews said as much. For a fuller sense of where each temperature band earns its keep, the temperature guide covers the 100–220°C span both devices span between them.
About Dennis M.
Dennis M. has been reviewing vaporisers and vaping daily for the best part of a decade. He works in IT, has ADHD, and uses cannabis for chronic pain management. He lives in Manchester with his partner Sarah, who has now seen a vaporiser disassembled across a tea towel and would like assurances that this is a normal thing that people do.
Dennis would like it noted that he has used the same launderette on Wilmslow Road for eleven years and has been to a dry cleaner four times, all of them for the same suit. He is aware this is also his entire approach to owning vaporisers, and he'd thank you not to mention it.
A note on spelling: 'vaporizer' is the de facto international spelling, but I've stuck with the British 'vaporiser' throughout this blog.

A note on the strain test: the site-wide control is normally Jack Herer and Wedding Cake — same two jars, same grinder, across every device, so the strain is the control and the device is the variable. Neither of these two reviews ran that control. The Wolkenkraft Äris was tested on Gelonade (sativa hybrid, ~22–26% THC, limonene-dominant) and Curaleaf Gorilla Girl T24 (sativa hybrid medical, ~24% THC, caryophyllene-dominant). The Smono No.3 was tested on Apple Fritter (balanced hybrid, ~22–28% THC, caryophyllene-dominant) and Noidecs T20 Sativa Lemon Skunk (sativa medical, ~20% THC, limonene-dominant). The comparison above is therefore by terpene family, not like-for-like, and is flagged as such where it appears. Strain effects vary by individual, batch and consumption method.
