DaVinci Micro (MIQRO-C) Review: The Swiss Army Knife Keychain of Vaporisers

The Hook: Swiss Army Knife Keychain

You know the one. Not the big Swiss Army Knife with the saw and the corkscrew and the thing that's allegedly for removing stones from horses' hooves. The little one. The keychain model. Tiny scissors. Toothpick in the side. Nail file. Fits between your car key and your house key and you forget it's there until you need to open an envelope and suddenly it's the most useful thing you own.

But nobody carves a Sunday roast with the keychain model. Nobody pretends the tiny scissors can cut fabric. Nobody uses it as their primary knife because it's not a primary knife. It's a backup. An emergency tool. The thing you're grateful to have when you don't have anything else.

The DaVinci Micro is that keychain knife. 87 grams of sandblasted aluminium with a 100% zirconia ceramic vapour path that delivers flavour rivalling devices three times its size. Smart Paths. 1-degree precision. USB-C. Everything DaVinci does well, miniaturised into something that fits in a coin pocket.

And then the battery lasts thirty minutes. And you remember the big knife is at home on the counter.

I own the ArGo. I called it the Brompton Bike of vaping. The Micro makes the ArGo look like a Penny Farthing. I took the Micro to the cinema three times before I realised I'd been bringing the ArGo for no reason. Then the battery died mid-film and I switched back.

We stock the DaVinci MIQRO-C at HerbVape.co.uk — details and pricing below.

Vapour Quality 7.0/10

The zirconia path doesn't care about the device size. It delivers.

First draw at 170°C: clean, bright, properly flavourful. Close your eyes and you'd think you were drawing from the IQC. The 100% zirconia ceramic vapour path is identical in material to DaVinci's flagships, and it tastes like it. The first two draws from the Micro are genuinely excellent — terp-rich, smooth, zero off-flavours.

By draw three, the 0.25g bowl is giving up its secrets. Conduction has done its thing — walls first, centre catching up. By draw four, you're extracting rather than tasting. Total useful draws: 3-4 at low temps, maybe 5-6 if you step up to 200°C+.

The bowl is the limiter, not the path. 0.2-0.3g through zirconia produces beautiful flavour while it lasts. It just doesn't last long. This is the keychain scissors — excellent for the envelope, not the Sunday roast.

Vapour density is moderate. You're not getting the thick clouds of a Mighty+ 0.2g load, because the Micro's smaller oven and lower thermal mass mean less energy driving the extraction. Light to moderate visible vapour. Enough to know it's working. Not enough to impress Dave.

The Strain Test

Two strains. Two very different envelopes. The keychain scissors don't care what you're cutting.

Cherry Pie — Indica Hybrid (Street)

The Flower: Granddaddy Purple × Durban Poison. 70% indica, 30% sativa. 16-24% THC. Myrcene, caryophyllene, limonene, linalool. Sweet cherry, berry pie crust, herbal undertones. The name isn't marketing — it genuinely tastes like cherry pie at low temps. One of the most flavour-forward indica hybrids available.

The Pack: 0.2g fine grind, no capsule, gentle tamp.

Smart Path: Flavour (340-380°F / ~171-193°C): Cherry. Actual cherry. The zirconia path captures Cherry Pie's signature terpene with startling clarity. Two draws of sweet, berry-pie-crust flavour that would embarrass some full-size devices. The linalool adds a floral edge underneath. This is the Micro at its absolute best — concentrated flavour in a micro-dose.

Mid Temp (190°C manual): The caryophyllene warms things up. Peppery, deeper, the pie crust rather than the filling. Two draws. Effects settling — gentle indica relaxation without couch-lock.

High Temp (210°C manual): One draw to finish. Earthy, herbal. ABV is medium-brown — not fully extracted, but the Micro doesn't have the thermal mass for total extraction. That's fine for a microdose session.

The Verdict: Cherry Pie through the Micro is a masterclass in concentrated flavour. 0.2g through zirconia delivered more flavour per gram than most devices deliver per session. Five draws over six minutes. The cherry came through clean. The keychain scissors opened this envelope beautifully.

Noidecs T23 Green Gelato — Sativa Hybrid (Medical)

The Flower: Thin Mint GSC × Sunset Sherbet, sativa-leaning phenotype. 23% THC. Limonene, caryophyllene, myrcene, humulene. Sweet, citrusy, minty cookie with earthy undertones. Complex profile that rewards low-temp extraction. At 23% THC, this is the high-potency medical option.

The Pack: 0.25g medium grind, capsule. Testing precision dosing.

Smart Path: Flavour: Mint-citrus opening — the limonene cuts through clean and bright. The gelato lineage brings sweet cookie undertones by draw two. The capsule helps even extraction in the tiny chamber. Two excellent draws.

Precision Mode: 180°C (flat hold): Camped at 180°C rather than stepping. Three consistent draws of balanced gelato flavour. The sativa effects kick in — cerebral, alert, focused. At 23% THC in a 0.25g micro-dose, the functional effects are noticeable without being overwhelming. This is the Micro doing medical microdosing — measured, precise, controlled.

Stepped to 200°C: The cookie earthiness emerges. Caryophyllene brings warmth. Two draws. Session complete. Total: seven draws over eight minutes.

The Verdict: 23% THC in a 0.25g capsule through 1-degree precision temperature control. This is the Micro's medical argument: you can micro-dose a potent medical strain with genuine accuracy. The capsule system makes doses repeatable. The precision mode means you can find and bookmark your exact sweet spot. For ADHD microdosing specifically, this is one of the best tools in the price range.

Design & Build (The 'Coin Pocket' Story) 8.0/10

I put the Micro in my coin pocket. It fit. It actually fit. 23 × 34 × 80mm, 87 grams. This is the most portable premium vaporiser I've tested, and it's not even close.

The sandblasted aluminium is the same finish as the IQC — fingerprint-resistant, dense, cool to the touch. At 87g, the Micro weighs less than most smartphones without a case. The build quality is disproportionate to the size — it feels like someone miniaturised a proper device rather than built a small cheap one.

The 18350 battery compartment is functional but fiddly. The tiny battery requires aligning the positive terminal correctly, and the contact springs need occasional cleaning. This is where "Swiss precision" meets "tiny fiddly things" — elegant in concept, annoying in practice at 11pm with cold fingers.

Battery & Charging (The IT Guy Check) 4.5/10

Thirty minutes. Three sessions. That's the Micro's battery life and there's no escaping it.

The 18350 cell delivers 900mAh. In a device with a 150-221°C oven and a 40-50 second heat-up, that translates to approximately thirty minutes of actual vaping time. Three sessions of 8-10 minutes, or two longer sessions with temperature stepping.

Battery recognition failures are documented and recurring. Remove the 18350, reinsert it, try again. Sometimes it works first try. Sometimes it takes five attempts. The contact springs in the battery compartment are the suspected culprit — a design issue that cleaning helps but doesn't solve permanently.

The MIQRO-C upgrade: USB-C charging replaces the original's Micro-USB. This matters — Micro-USB ports were the original model's Achilles heel, with loose connections and failed charges. USB-C is more reliable, charges faster, and uses the cable you already carry. It's the primary reason to buy the MIQRO-C over the original.

The removable battery saves the score from a 3. Carry two spare 18350s and you've got ninety minutes of vaping. The batteries cost £5 each. The PAX Mini 2 has a sealed 1500mAh — you can't swap it when it dies. The Micro's removable cell is the Swiss Army Knife's spare blade: tiny, essential, the only reason this approach works at all.

Ease of Use 7.5/10

The device itself is simple: Smart Paths plus Precision mode, same as the IQC family. Four preset curves or manual 1-degree control. Press, wait, draw.

The battery adds friction. Every session starts with "will it recognise the battery?" If yes — smooth, simple, five seconds from pocket to session. If no — remove battery, reinsert, try again, check orientation, try again, question your life choices, try a different battery, success on attempt four. That friction erodes the elegance of everything else.

Loading the tiny chamber is easier than expected. The 0.25g bowl doesn't need precision packing. Medium grind, light pour, done. The capsule system adds convenience and repeatability for medical dosing.

Cleaning & Maintenance 7.5/10

Small device, small chamber, small cleaning job.

The tiny zirconia chamber takes thirty seconds to brush clean. There's no cooling unit. No Devil's Arse. No labyrinthine vapour maze to excavate with Q-tips and determination. Brush the chamber, soak the mouthpiece in ISO weekly, done.

The zirconia doesn't stain as aggressively as metal. After a month of daily use, it's darker but not caked. A proper ISO soak returns it to near-new condition.

This is the Micro's quiet advantage — the cleaning that doesn't happen. You spend thirty seconds maintaining it rather than thirty minutes. For people who've owned a Mighty+ and dreaded cleaning day, the Micro feels like a holiday.

Portability 9.5/10

The most portable premium vaporiser I've tested. Period.

87g. 23 × 34 × 80mm. This fits in a coin pocket. This fits in that tiny fifth pocket on jeans that nobody knows the purpose of. The ArGo is bigger. The PAX Mini 2 at 89g is barely lighter but significantly taller. The Crafty+ is a brick by comparison. Nothing else comes close.

The sandblasted aluminium in your palm feels like holding a Zippo lighter. People won't know what it is unless they're looking for it. The flat mouthpiece mode makes it slimmer. In a jacket's inside pocket, it genuinely disappears.

I took it to three films, two pub quizzes, and one awkward family dinner. Nobody noticed. Nobody asked. That's the portability promise, and the Micro delivers on it completely.

Dennis M. — on the coin-pocket test

The half-point off a perfect 10? Battery. The most portable device in the world is useless when it's dead. And with thirty minutes of life, "dead" arrives fast.

How I Actually Use This

My Default Setup:

• Temperature: Precision mode, 180°C flat hold
• Pack: 0.2g fine grind, capsule
• Session: 6-8 minutes, 4-6 draws

When I Reach For It: Cinema. Quick walks to the shop. Pub quizzes where pulling out a Mighty+ would be conspicuous. Any situation where I need a vape in my pocket and don't want to think about it taking up space. The Micro is the "I might want a session later" device — small enough to carry without committing to using it.

When I Don't: Literally everything else. Home use: Mighty+. Going out: Crafty+. Weekend flavour sessions: TinyMight 2. The Micro supplements. It doesn't replace.

Battery Management: I carry two spare 18350s in a small silicone case. The case cost £3 on Amazon. Without it, the Micro is a thirty-minute device. With it, I've got ninety minutes of vaping and sixty seconds of battery-swapping frustration. Acceptable trade-off.

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 Micro is a breakthrough device, not a primary one. When pain flares up on the commute, at work, or in a social situation — the Micro is the device small enough to have on you. 0.2g of a high-THC indica through the zirconia path delivers noticeable pain relief in 3-5 minutes. Not sustained multi-hour relief, but enough to get you home to the bigger device.

For ADHD: This is where the Micro genuinely excels. The 0.25g capsule system with 1-degree precision temperature control is a legitimate microdosing tool. Green Gelato at 180°C delivered exactly the functional focus I was looking for — alert, calm, productive. The Micro's small bowl prevents over-medication, which is the microdosing discipline that devices with bigger bowls don't enforce.

Value for Money 7.0/10

£99 for a zirconia-pathed, precision-temp, removable-battery pocket vape is fair. The materials are premium. The engineering is genuine. The DaVinci pedigree is real.

The calculation that complicates things: The ArGo is £123.99 with a significantly better battery life and glass vapour path. The PAX Mini 2 at £109 has a sealed battery but double the capacity. At £99, the Micro isn't overpriced — but the neighbourhood is competitive.

What £99 buys: 87g of genuine DaVinci quality with a 5-year warranty. If portability is your #1 priority and nothing else comes close — and nothing does — the Micro earns its price. If portability is important but not paramount, the ArGo offers more complete daily-use functionality for twenty-five quid more.

Score Breakdown

Vs the Competition

Vs Arizer ArGo (£123.99)

The comparison that matters most. The ArGo has better battery life, a glass vapour path, and a more complete daily-driver package. The Micro is smaller, lighter, and has precision temp control. Twenty-five pounds separate them. For most people, the ArGo is the better buy. For pure portability purists, the Micro wins. DaVinci Micro vs ArGo.

Vs PAX Mini 2 (£109.00)

PAX Mini 2 at 89g is barely heavier with a 1500mAh sealed battery — double the Micro's life. But no temp precision and conduction-only with PAX's experience modes. The Micro extracts better. The Mini 2 lasts longer. Design versus function. DaVinci Micro vs PAX Mini 2.

Vs XVAPE Lanza (£48.00)

Half the price, same general concept (small, simple, conduction), but without the zirconia path or temp precision. The Lanza is the backup to the backup. The Micro is the premium pocket option.

Specifications

The Verdict (The Bookend)

Keep one in your jacket. Don't sell your kitchen knives.

The Swiss Army Knife keychain model has saved me exactly four times in my life. An envelope. A loose thread on my shirt collar. A splinter in my thumb. And a price tag that wouldn't tear off a Christmas present. Four moments where the big knife was at home and the tiny one was in my pocket and I was grateful.

The DaVinci Micro has saved me in the same way. Three cinema trips. Two pub quizzes. One family dinner where I needed five minutes in the garden. Moments where the Mighty+ was at home, the Crafty+ was too conspicuous, and the Micro was just... there. In my coin pocket. 87 grams. Zirconia. Ready.

For thirty minutes.

Just one more bowl.
