Vaporizer Review
XMAX Ace Review: The Lidl Middle Aisle Find of Vaporisers
"You went in for milk and bread. You came out with a vaporiser that empties its own bowl."

The XMAX Ace is a budget conduction vaporiser with one genuine party trick: a self-cleaning button that empties the bowl at the push of a spring-loaded plate. It suits people who hate cleaning and want removable 18650 batteries for under eighty quid.
- Score: 7.2/10
- Best for: People who hate cleaning, budget-conscious users who want a swappable 18650, and simplicity-first first-timers
- Skip if: You chase flavour (the display lies by 20-25°C), demand premium build, or already eye the XMAX V3 Pro
- Price: £79.00
A Lidl middle aisle find: surprisingly good, slightly rough, and absolutely worth the money.
The Good
- Self-cleaning button genuinely works — push the spring-loaded mechanism and the bowl empties itself. No scraping, no digging, no post-session ritual. This is the Ace's reason to exist.
- Removable 18650 battery — 2600mAh gives ~10 sessions and 75 minutes continuous. Swap in a fresh cell and keep going.
- 20-second heat-up — faster than most competitors in this price bracket. Quick sessions are actually quick.
- Haptic feedback — vibrations tell you when it's ready, when the session's ending, when boost activates. Thoughtful touches for under £80.
- 1-degree temperature control — a wide 100-240°C range with a 255°C boost. More control than you'd expect at this price.
The Bad
- Temperature display reads 20-25°C high — when it says 210°C, you're vaping at ~190°C. Documented and significant. You're chasing flavour with a compass that's off by twenty degrees.
- Carbon fibre finish is cosmetic, not premium — a plastic housing with a carbon-fibre sticker. At 340g, it's surprisingly heavy for what it delivers.
- MicroUSB in 2026 — the V3 Pro has USB-C. The Lanza at half the price has USB-C. There's no excuse.
- The self-cleaning mechanism has moving parts — spring-loaded mechanisms and sticky resin are not natural allies. Long-term durability is the open question.
- Combustion risk at 255°C boost — the max temp is genuinely too hot. Stay below 240°C unless you enjoy the taste of charcoal.
The Hook: Lidl Middle Aisle
You went in for milk. Maybe bread. Possibly those yoghurts Sarah likes, the ones in the blue pot. You know the ones.
And then you walked past the middle aisle. The aisle that has no logic, no consistency, and no right to contain a pneumatic drill next to a children's wetsuit next to a sommelier's corkscrew. The aisle where Germany's finest retail minds decided that the best sales strategy is confusion.
And there it is. A thing. You don't know what it does. It costs less than you'd expect. The packaging is... functional. The description is in four languages, three of which you don't speak. But something about it — the feature list, maybe, or the price tag, or the sheer audacity of finding it between the dog beds and the protein bars — makes you put it in the trolley.
You get home. You use it. It works. Not just works — works well. One specific feature is genuinely impressive, the kind of thing that makes you wonder why the expensive brands haven't thought of it. You tell your mate about it. They don't believe you. You show them. They buy one.
That's the XMAX Ace. The self-cleaning button is the middle aisle cordless drill moment. You didn't know you needed a vaporiser that empties its own bowl until you pushed the button and watched the herb fall out and thought "why doesn't every vape do this?" Because every vape should do this. And none of them do. Except the Ace. For eighty quid.

But the display temperature is twenty degrees off. And the carbon fibre is a sticker. And it charges via MicroUSB. Welcome to the middle aisle. The highs are high. The lows are part of the deal.
We stock the XMAX Ace at HerbVape.co.uk — details and pricing below.
Vapour Quality 7.0/10
Let me address the temperature issue immediately: the display reads 20-25°C higher than the actual oven temperature. When you set it to 210°C, you're vaping at approximately 190°C. When you set it to 190°C, you're at 170°C. This is documented across multiple owners and review sites.
Dave was the first to notice. "It says 210 but it tastes like 190. Something's off." Dave has used enough devices to know when the numbers don't match the experience. And he's right — the numbers don't match.
Once you adjust for the offset, the vapour is decent. The black ceramic chamber delivers clean conduction with no metal taste. The zirconia mouthpiece (which swivels for pocket storage — nice touch) adds a layer of vapour cooling. At corrected temperatures, the flavour is honest and functional if not spectacular.
The 0.35g bowl is a good size — large enough for a proper session, small enough for efficiency. Conduction means you'll want to stir mid-session for even extraction, but the self-cleaning mechanism actually helps here: a partial push agitates the herb without fully ejecting it.
The rubber in the mouthpiece lid affects taste purity. Compared to the Smono 3's glass mouthpiece or the IQC's zirconia path, the Ace has a slight warmth to the flavour that comes from rubber, not terpenes. It's subtle, but it's there.
The Strain Test
Two strains. Two middle aisle surprises. Remember to add 20°C to every temperature you set.
Forbidden Fruit — Indica (Street)
The Flower: Cherry Pie × Tangie. 70% indica. 21-26% THC. Myrcene, limonene, caryophyllene, pinene. Tropical mango, cherry, grapefruit with earthy pine finish. One of the most exotic-tasting indicas available — complex fruit terps that deserve a clean vapour path. Dense, colourful buds with purple hues. The strain that looks so good you almost don't want to grind it.
The Pack: 0.3g medium grind, no capsule.
Set 190°C (Actual ~170°C): The limonene lifts immediately — tropical, mango-sweet, bright. Forbidden Fruit's terps have low boiling points, which means even the Ace's cooler-than-displayed actual temperature captures them. Three draws of genuine tropical fruit complexity. The offset actually helps here — you're gently extracting at what's really a low temp, preserving volatile terps that a true 190°C would cook off.
Set 210°C (Actual ~190°C): Cherry and caryophyllene come forward. Peppery warmth underneath the fruit. The indica body settles. Three good draws with increasing density. Stirred the bowl at this point — the partial self-clean push agitated the herb nicely.
Set 230°C (Actual ~210°C): Earthy pine finish from the pinene. Full indica extraction. Two draws to complete. AVB medium-brown.
The Verdict: Forbidden Fruit's tropical terps survived the Ace's temperature offset and came through with surprising clarity at the corrected low temps. The offset is a feature if you know about it and a flaw if you don't.
Pro tip: Set your temperature 20°C higher than you normally would. The Ace's display and your expectations will eventually align — usually within a week of daily use.
Grow Pharma Strawberry Glue — Hybrid (Medical)
The Flower: Strawberry Cough × Gorilla Glue #4. Balanced hybrid. 20-22% THC. Myrcene, caryophyllene, limonene, pinene. Sweet strawberry meets diesel/earthy glue. The crossover strain that bridges recreational and medical — Strawberry Cough sweetness makes GG4 potency approachable. Notably resinous — the GG4 genetics produce sticky, screen-clogging flower.
The Pack: 0.35g medium grind, full bowl. The resin test.
Set 185°C (Actual ~165°C): Strawberry sweetness — gentle, clean, approachable. The low actual temperature pulls the Strawberry Cough parentage out first. Two draws of sweet, functional vapour. Effects are mild at this range — daytime-friendly.
Set 200°C (Actual ~180°C): The GG4 glue complexity arrives. Diesel, earthy, sticky. The caryophyllene provides that peppery CB2 warmth. Three draws, increasing density. Effects settling into balanced hybrid territory — functional pain relief with mood uplift.
Set 220°C (Actual ~200°C): Full extraction. Earthy, herbal, heavy. Two draws. AVB is properly extracted.
The Self-Cleaning Test: After the session, pushed the self-cleaning button. The spring-loaded mechanism ejected the AVB cleanly — even from GG4-lineage resinous flower. Some residue stuck to the chamber walls (inevitable with Gorilla Glue genetics), but the bulk of the AVB ejected. The screens, however, were gunked. After two sessions with Strawberry Glue, the screens needed manual cleaning. The self-cleaning button handles the herb, not the resin.
The Verdict: Strawberry Glue revealed the self-clean's limitations: it empties herb but not resin. The screens still clog with sticky flower. The self-cleaning is real but partial. For low-resin flower, it's a revelation. For GG4-level stickiness, you're still cleaning screens manually.
Design & Build 6.5/10
The carbon fibre finish isn't carbon fibre. Let's get that out of the way. It's a textured plastic housing with a carbon-fibre-pattern finish. At 340g, it's surprisingly heavy — heavier than it looks, heavier than it should be. The weight doesn't come from premium materials; it comes from the spring-loaded self-cleaning mechanism adding mass.
The swivel zirconia mouthpiece is a genuine design win. It tucks flat against the body for pocket storage, swivels out 90° for use. Smart engineering that reduces snag points. The zirconia stays cool enough to touch comfortably.
The self-cleaning mechanism is the engineering achievement. A spring-loaded plate at the bottom of the chamber, activated by a button push, physically ejects the AVB. It's satisfying in the way that clicking a retractable pen is satisfying. Push, click, herb falls into your AVB container. Done.
Long-term durability is the open question. Spring-loaded mechanisms in environments with sticky resin and heat are not historically reliable. After a month of daily use, the mechanism still clicks cleanly. Ask me again in six months.
Jake heard about the self-cleaning button. "Wait — you mean I don't have to clean it?" You still have to clean it, Jake. The button just empties the bowl. "...Close enough."
Battery & Charging 7.5/10
Removable 18650 is the right call for a device at this price. 2600mAh delivers approximately 10 sessions and 75 minutes of continuous use. Solid numbers that compete with devices costing twice as much.
MicroUSB is the wrong call for a device in 2026. The XMAX V3 Pro — from the same manufacturer — has USB-C. The Lanza at literally half the price has USB-C PD3.0. The Ace's MicroUSB feels like an oversight or a cost-cutting decision that ages the device immediately.
Charge time: 2-3 hours via MicroUSB. Acceptable if you have spare batteries. Frustrating if you don't. The removable cell means you can charge externally with a dedicated 18650 charger (faster, more reliable, better for battery longevity).
The spec check:
- USB-C: No (MicroUSB)
- Fast Charging: No
- Pass-Through: Unknown
- Replaceable Battery: Yes (18650)
Ease of Use 8.5/10
The self-cleaning button transforms the daily routine.
Traditional vape workflow: grind, load, vape, cool down, brush chamber, tap out AVB, brush again, repeat. The Ace's workflow: grind, load, vape, push button, done. The herb falls out. The chamber is mostly clear. Move on.
That simplification matters more than spec sheets suggest. The friction of vaping isn't the vaping — it's the before and after. The Ace removes half the "after." Over a week, over a month, over a year of daily use, that accumulated time savings is the Ace's real selling point.
Haptic feedback is a nice touch. Vibration when ready, vibration at session end, vibration on boost activation. For under £80, these are thoughtful additions that suggest someone at the manufacturer actually uses vaporisers.
20-second heat-up is fast. 1-degree temperature control gives granular precision (even if the display lies about the actual temp). Session mode and on-demand mode offer flexibility.
Mum test — borderline pass. The self-cleaning button is genuinely mum-friendly. She'd never know about the temperature offset — and for Mum, that probably doesn't matter. She'd set it to preset 3 and leave it. "Mum could empty it. That's more than most devices can claim."
Cleaning & Maintenance 8.0/10
The self-cleaning mechanism earns its score. After each bowl, one push ejects the AVB. No brush. No scraping. No fuss. For low-to-moderate-resin flower, the chamber stays remarkably clean.
The screens still clog. This is the "half a job" reality. The button empties the herb; it doesn't clean the screens, the airpath, or the mouthpiece. After 3-5 sessions, the screens need manual cleaning — soak in ISO, brush, replace. The self-cleaning postpones the deep clean but doesn't eliminate it.
Cleaning timeline:
- After every bowl: push the button (2 seconds)
- Every 5 sessions: clean the screens (5 minutes with ISO soak)
- Weekly: mouthpiece ISO soak and full screen replacement if needed
- Monthly: deep clean airpath and mechanism
Compared to the Mighty+ cooling unit teardown or the IQ3's deep-clean excavation, the Ace's maintenance is significantly less demanding. The self-cleaning button doesn't do everything. But what it does, it does well.
Portability 7.5/10
Compact dimensions (99 × 43 × 24mm) suggest pocket-friendliness, but 340g is heavy for a portable. You know the Ace is in your pocket. It's not uncomfortable, but it's present.
The swivel mouthpiece helps — tucked flat, the profile is smooth and snag-free. The carbon fibre finish (cosmetic or not) is reasonably grippy without collecting lint like silicone.
Stealth is moderate. The Ace doesn't look like a vape from across the room, but it doesn't look like anything else either. The carbon fibre pattern and industrial shape suggest "electronic gadget" rather than "medical device."
How I Actually Use This
My default setup:
- Temperature: Set 210°C (actual ~190°C). The mental maths becomes second nature.
- Pack: 0.3g medium grind, loose.
- Session: 8-10 minutes, 6-8 draws with a mid-session stir.
When I reach for it: When I can't be bothered with cleanup. Genuinely. Some evenings — pain flaring, fatigue kicking in, ADHD brain refusing to engage with a multi-step maintenance ritual — the Ace's "push and done" emptying is the difference between having a session and not. The self-cleaning isn't a gimmick. It's an accessibility feature for days when regular cleaning feels like climbing a mountain.
When I don't: When flavour matters. The temperature offset and rubber mouthpiece mean the Ace doesn't compete on pure taste. The Mighty+ and Solo 3 live on a different floor. The Ace is the device for function, not flavour.
The V3 Pro comparison: I already told you to buy the V3 Pro. At nearly the same price (£79.99), the V3 Pro heats better (hybrid versus conduction), charges better (USB-C versus MicroUSB), and extracts better. The V3 Pro is the better vaporiser. The Ace is the easier lifestyle. If you're disciplined about cleaning, get the V3 Pro. If you're honest about being lazy, get the Ace.
Medical Use Notes
I'm not a doctor. I'm a bloke with chronic pain and ADHD who's been using cannabis medicinally for years now. This is my experience, not medical advice. If you're considering medical cannabis, talk to a prescribing clinic — not a vaporiser review.
For pain management: The Ace delivers cannabinoids. The temperature offset means you need to compensate — set 20°C higher than your usual target. Once adjusted, the conduction extraction is adequate for pain relief. The self-cleaning feature has genuine medical accessibility value: on high-pain days, any reduction in post-session effort matters.
For ADHD: The simplified cleanup routine is the ADHD feature. Executive function struggles mean cleaning vaporisers falls into the "should do but can't face" category. The Ace's push-button emptying removes one friction point from the process. Not life-changing, but meaningful.
The boost warning: The 255°C boost mode will combust. For medical users who need precise dosing, combustion is the enemy. Stay below set 240°C (actual ~220°C) to be safe. The boost exists for extraction, not flavour or medical precision.
Value for Money 8.0/10
Eighty quid. Removable 18650. Ceramic chamber. Self-cleaning mechanism. Haptic feedback. 1-degree temperature control. Two session modes. Swivel zirconia mouthpiece.
Read that feature list without seeing the price and you'd guess £79-150. The XMAX Ace crams more features into £79 than most devices manage at double. Like everything in the Lidl middle aisle, the value proposition is aggressive and slightly bewildering.
The V3 Pro at £79.99 is the elephant in the room. Same manufacturer. A pound more. Better heating (hybrid vs conduction). Better charging (USB-C vs MicroUSB). Better regarded by the community. The V3 Pro is the device reviewers recommend. The Ace is the device lazy owners quietly prefer.
The self-cleaning is the tiebreaker. No other device at any price has a push-button bowl ejection. If that feature saves you ten minutes of cleaning per day, over a year that's sixty hours of your life back. What's that worth? More than a pound, probably.
Score Breakdown
| Category | Score | One-Line Summary |
|---|---|---|
| Vapour Quality | 7/10 | Decent conduction once you offset the temp. Rubber in the mouthpiece lid taints purity slightly. |
| Design & Build | 6.5/10 | Carbon fibre is cosmetic. 340g is heavy. The self-clean mechanism is genuine engineering. |
| Battery & Charging | 7.5/10 | Removable 18650, 10 sessions, 75 minutes. MicroUSB is inexcusable in 2026. |
| Ease of Use | 8.5/10 | Self-cleaning + haptic + fast heat-up = the simplest daily routine of any vape tested. |
| Cleaning & Maintenance | 8/10 | The button empties the bowl. The screens still clog. Half a job done brilliantly. |
| Portability | 7.5/10 | Compact but 340g is heavy. Swivel mouthpiece helps. Not stealth. |
| Value for Money | 8/10 | Feature-per-pound champion. The V3 Pro exists. The self-cleaning justifies the Ace. |
| Overall | 7.2/10 | Category average is 7.6 — adjusted down for the temperature inaccuracy which undermines trust in the device's precision claims. The self-cleaning is genuine innovation. Everything else is budget competence. |
Vs the Competition
Vs the XMAX V3 Pro (£79.99): Same manufacturer, a pound apart. The V3 Pro has hybrid heating (better flavour), USB-C (better charging), and stronger community approval. The Ace has self-cleaning (easier maintenance) and conduction (less technique). The V3 Pro is the better vaporiser. The Ace is the easier routine.
Vs the Starry 4 (£79.00): Same price bracket, same manufacturer. The Starry 4 has a more refined design and USB-C. The Ace has self-cleaning and a bigger feature list. The Starry 4 is the "safe" XMAX choice. The Ace is the "interesting" one.
Vs the Smono 4 Pro (£85.00): The Smono 4 Pro offers hybrid heating, ceramic chamber, 3000mAh battery, and a glass mouthpiece for six quid more. On paper, it's the better spec sheet. In practice, the Ace's self-cleaning is the feature the Smono doesn't have.
Vs the Boundless CFX (£119.00): Forty quid more for hybrid heating, a larger bowl, and a more established reputation. The CFX is the upgrade path for Ace owners who want better extraction but miss the self-cleaning.

The Verdict (The Bookend)
You'll tell your mates about it. They won't believe you. Then they'll try it. Then they'll buy one.
That's the Lidl middle aisle in one sentence. And that's the XMAX Ace. Nobody walks into a vape shop looking for a device with a self-cleaning button. Nobody puts "spring-loaded bowl ejection" on their wish list. But you push that button once — watch the AVB fall out, feel the satisfying click, realise you've skipped five minutes of post-session maintenance — and something shifts in your brain. Why doesn't every vape do this?
The temperature display lies. The carbon fibre is a sticker. The MicroUSB is an insult. But the self-cleaning button is real, the 18650 is swappable, and the price is eighty quid. Like everything in the middle aisle: the highs justify the compromises. You just have to accept both.
I went in for milk. I came out with a vaporiser that cleans itself. Classic middle aisle. Just one more bowl.
