Smono No.5 Review: The Tesco Finest of Vaporisers

The Hook: Tesco Finest

Jake loved the removable battery concept. "Infinite power!" he announced, sliding the Samsung 18650 into the compartment with the confidence of a man loading a pistol magazine.

Then he immediately lost the battery door spring in his carpet.

He's held it together with a rubber band ever since.

That's Tesco Finest energy. You open the packaging and think: this is genuinely impressive for the price. The OLED display glows with information. The Smart Puff technology sounds like something from a device twice the cost. The removable 18650 slides in with a satisfying click. The ceramic chamber is clean. The glass mouthpiece is premium.

Then the battery door starts wobbling. Not today. Not this week. But give it six months of daily use — six months of opening, swapping, closing, opening, swapping, closing — and you'll feel it. The latch loosens. The door rattles. The wobble becomes a feature of the device rather than a flaw in the design. Like Tesco Finest: everything else is great, but that one thing bugs you.

The OLED display is pure Tesco Finest energy — a premium-looking label on a product that costs a fraction of the "proper" brands. Smart Puff Identify is the "6-hour slow-cooked" sticker — it actually works, against all expectations. And the removable battery is the reusable packaging — practical, sustainable, genuinely forward-thinking.

Vapour Quality 7.0 / 10

Conduction with Smart Puff assist. The ceramic chamber heats the herb through contact, and the Smart Puff technology detects your draws to boost heating during inhales, maintaining consistent temperature despite airflow cooling.

At 180°C, the first three draws are good. The ceramic chamber is neutral — no stainless steel tang, no aluminium warmth. Through the glass mouthpiece, the vapour is clean and reasonably flavourful. Smart Puff keeps the temp stable during draws, which extends the flavour window by a draw or two compared to standard conduction.

By draw four, conduction takes over. Flavour drops. The herb near the walls is extracted; the centre needs stirring. Smart Puff can't change physics — it can only maintain temperature, not redistribute heat.

At 200°C, decent density. Visible clouds. Good extraction. At 220°C+, full extraction with diminished flavour. The wide range (up to 240°C) is there for extraction completeness, not flavour quality.

The 0.3g bowl is a good middle ground — not micro-dose small, not session-bowl large. Two bowls per evening session is typical.

The Strain Test

Two strains. Two Finest flavours. Both adequate, one surprisingly good.

Kush Mints — Hybrid (Street)

The Flower: Animal Mints × Bubba Kush. Indica-leaning 60/40 hybrid. 22–27% THC. Limonene dominant, caryophyllene, linalool, myrcene. Minty cookie dough, diesel exhale, earthy kush. The mint comes in waves — first draw is cookie, second is mint, third is diesel.

The Pack: 0.3g medium grind, full ceramic chamber.

180°C: Mint. Immediate and sharp. The limonene-linalool combination through ceramic and glass produces a clean, cool menthol opening. Smart Puff kicks in on the draw, maintaining 180°C through the inhale. Three draws of surprisingly bright mint character. The volatile minty terpenes are preserved — a low start was critical.

195°C: Cookie dough. The Animal Cookies parentage deepens — buttery, sweet, doughy. The caryophyllene adds warmth. Stirred at draw four. Two more draws post-stir. The transition from mint to cookie to diesel is the strain's signature, and the No.5 captures the progression.

210°C: Kush foundation. Earthy, heavy, indica body. Two draws. Full extraction.

The Verdict: Kush Mints at 180°C through the No.5 was a genuine surprise — the mint terpenes came through clearly enough to be distinctive. Smart Puff's temperature maintenance during draws helped preserve the volatile mint notes. For a conduction device, this is above-average terp preservation. The Smono No.3's convection would pull more nuance, but the No.5's battery lets you session longer.

Curaleaf Orange Skunk T20 — Sativa (Medical)

The Flower: Orange Bud × Skunk #1. Sativa-dominant. 20% THC, <1% CBD. Limonene, myrcene, pinene. Bright orange citrus, skunky background, piney fresh finish. Punchy limonene. At ~£7–8/g, a well-known medical sativa.

The Pack: 0.25g medium grind, slightly under full.

175°C: Orange citrus. Bright, immediate, clean. The limonene through ceramic is honest — no chamber interference, no flavour addition. Two draws of good sativa clarity. Smart Puff maintaining temp. Effects are focused, alert, functional.

190°C: Balanced effect. Skunky undertone arriving. Pinene sharpness. Three draws. The sativa focus deepens — a good ADHD productivity strain at this extraction point.

200°C: Full extraction. Earthy, herbal. One draw to finish.

The Verdict: Orange Skunk's strong limonene survived the conduction + Smart Puff treatment. The No.5 extracted the citrus character adequately — not with the precision of the Smono No.3's convection, but clearly enough for medical patients to taste their strain. For daily medical use, the removable 18650 battery is the real advantage — the device is always ready.

Design & Build 6.0 / 10

The OLED display looks premium. The glass mouthpiece feels premium. The removable battery system is clever. The overall design is considered and modern.

The battery door latch is not. This is the Smono No.5's documented Achilles heel. The mechanism that holds the battery compartment closed wears with use. Daily users report rattling by month three to six. The wobble doesn't affect function — the battery still makes contact, the device still fires — but it feels fragile. It sounds fragile. It erodes confidence.

Jake's rubber band solution is extreme. Most users tolerate the wobble. But a device with a £99 price tag shouldn't need tolerating.

Battery & Charging 9.0 / 10

Removable 18650. 3000mAh Samsung cell. This is the best battery system in the Smono range and one of the best in the entire mid-range.

Swap cells in seconds. Carry spares for infinite sessions. When the cell degrades, buy a new one for £5. External chargers are faster and healthier than USB-C device charging. Dave's three-cell rotation system works perfectly: use one, charge two.

The Spec Check:

• USB-C: Yes
• Fast Charging: Standard USB-C (~90 min)
• Pass-Through: Not recommended
• Replaceable Battery: Yes (18650, 3000mAh Samsung)

Ease of Use 7.0 / 10

The OLED display makes temperature selection intuitive. Degree-by-degree control from 160–240°C. Smart Puff Identify adds auto-heating on draw. Glass mouthpiece.

Smart Puff has a learning curve — it occasionally false-triggers on early firmware, activating heat without a real draw. Updated firmware (v5.4) mostly resolves this. But the concept works: draw and the device heats. Stop drawing and it throttles. It's clever enough to be useful.

The stirring requirement is the usual conduction annoyance. The battery door mechanics add a step that simpler devices don't have.

Cleaning & Maintenance 6.0 / 10

Standard ceramic chamber cleanup. Glass mouthpiece soaks clean. The airpath is less accessible than the Smono No.3's titanium setup.

The mouthpiece gasket needs monitoring — frequent removal for cleaning accelerates gasket degradation. Replace annually.

Cleaning timeline:

• After every session: brush the ceramic chamber
• Every 5–7 sessions: ISO soak the glass mouthpiece and screens
• Weekly: check battery door contacts, clean with a dry cloth
• Monthly: full disassemble, inspect gaskets, deep clean

Portability 7.0 / 10

~150g, compact handheld. The battery adds a touch of bulk versus sealed-battery devices. Pocket-friendly for jackets, manageable for jeans.

The OLED display is readable in most conditions (it struggles in direct sunlight). The glass mouthpiece adds fragility for pocket carry.

How I Actually Use This

My Default Setup:

• Temperature: 190°C. A good balance of flavour and density.
• Pack: 0.3g medium grind, full chamber.
• Session: Smart Puff auto-heating, stir at halfway.

When I Reach For It: When I need all-day battery with swap capability. The removable 18650 means I can vape all day — three cells, three rotations, zero anxiety. For days out, festivals, or situations where charging isn't available, the No.5's battery system is unmatched under £120.

When I Don't: When flavour matters more than battery life. The Smono No.3 at £75 has better convection flavour. The Roffu at £109 has better convection flavour AND a removable 18650. The No.5's advantage is specifically the combination of OLED, Smart Puff, and swappable battery in one package.

Medical Use Notes

For Pain Management: The removable battery means the device is always ready for pain episodes. The OLED display shows exact temperature for consistent dosing. Smart Puff maintains temp during draws for reliable extraction. The 3-year warranty provides coverage for medical patients.

For ADHD: The OLED is easy to read. Smart Puff removes one decision (when to draw — just draw). But the battery door complexity and stirring requirement add executive-function demands. Mixed for ADHD.

Value for Money 8.0 / 10

At £99, the No.5 delivers: removable 18650, OLED display, Smart Puff tech, ceramic chamber, glass mouthpiece, wide temp range, 3-year warranty. The spec list is competitive.

But the pricing is awkward. The Smono 4 Pro at £85 offers hybrid heating and a sealed 3000mAh battery. The Roffu at £109 offers true convection, dual chambers, and a removable 18650 for a tenner more.

The No.5's value lives in its specific combination: OLED + Smart Puff + swappable 18650. If you want all three, nobody else offers this at £99. If you're flexible on any one feature, cheaper alternatives exist.

Score Breakdown

Vs the Competition

Vs Smono 4 Pro (£85.00): Fourteen quid less for hybrid heating, a 3000mAh sealed battery, OLED, and a ceramic zirconia chamber. The No.5 has a removable battery and Smart Puff. The 4 Pro is better value for most users. The No.5 wins only on battery swappability.

Vs XLUX Roffu (£109.00): A tenner more for true convection, dual chambers, a removable 18650, OLED, and session + on-demand modes. The Roffu is more capable. The No.5 has Smart Puff and arguably simpler operation, but the Roffu is the better device.

Vs Smono No.3 (£75.00): Twenty-four quid less for pure convection, a titanium chamber, and a glass mouthpiece. The No.3 has better flavour. The No.5 has a removable battery, OLED, and Smart Puff. Flavour vs features.

Vs PAX Mini 2 (£119.00): Twenty quid more for PAX design, 89g portability, and lip-sensing tech. The PAX is smaller and prettier. The No.5 has a removable battery, OLED, and better temp control. Different priorities.

The Verdict (The Bookend)

The battery door is the Finest ready-meal with slightly soggy pastry. Everything else is great. That one thing bugs you.

The Smono No.5 is a good device. The removable 18650 with 3000mAh is the best battery system in the budget range. The OLED display is clear and useful. Smart Puff Identify genuinely improves draw consistency. The ceramic chamber and glass mouthpiece deliver clean vapour.

But the battery door wobbles. And the Smono 4 Pro costs fourteen quid less with hybrid heating. And the Roffu costs a tenner more with true convection and dual chambers. The No.5 exists in a market where its price doesn't quite justify its advantages over cheaper, more capable alternatives.

If the removable 18650 + OLED + Smart Puff combination is exactly what you want, the No.5 is the only device that delivers all three. If you're flexible on any one of those features, the competition is friendlier.

Nobody believes the Tesco Finest price tag until they try it. But sometimes the pastry's soggy.

Just one more shelf.
