Two kits, one identical promise: 6,000 puffs. One battery you keep reusing with fresh pods, one you toss and replace. If you are standing in a UK vape shop staring at the shelf, here is the question that actually matters: does the extra £5 on the Lost Mary buy you a better vape, or just a prettier box?
The 60-second verdict
Pick the Hayati Pro Max Plus if you want the best value per day. It has the bigger battery (850mAh vs 650mAh), cheaper ongoing refills (£5.49 replacement pods instead of buying a whole new kit), and a wider flavour menu.
Pick the Lost Mary BM6000 if flavour intensity and design are your priority. Its QUAQ mesh coil delivers the bolder, punchier first-hit taste Lost Mary built its name on, and the compact box-style body is the more pocketable of the two.
Both are mouth-to-lung, both run 20mg nic salts, and both last roughly a week of moderate vaping. The differences are in the details, which is what the rest of this comparison is for.
Same loophole, different engineering
Both kits exist because of the same UK rule. The TPD caps prefilled tanks at 2ml, so neither device holds 12ml in its working pod. Instead, each carries a 2ml active pod topped up automatically from a sealed 10ml reservoir or refill bottle. Same capacity, same compliance, different mechanics:
- Hayati Pro Max Plus: the 10ml reservoir is integrated into the pod assembly and feeds the 2ml pod by capillary action. No setup, no flipping, just click the pod in and draw.
- Lost Mary BM6000: the 10ml liquid comes as a separate bottle you slide into the base of the device, then you hold the kit upside down for a few seconds to prime the pod.
The Hayati system is slightly simpler day to day. The Lost Mary system gives you a detachable battery block, which you can pop out for battery recycling when the kit is done, a small but genuine plus for anyone who disposes of vapes responsibly.
Also worth knowing: since October 2026, the Vaping Products Duty charges £2.20 per 10ml of e-liquid in the UK. That is roughly £2.64 on every 12ml kit, whether it is Hayati or Lost Mary, so street prices have edged up across the board.

Battery: the Hayati wins this round clearly
This is the least close contest in the comparison. The Pro Max Plus carries an 850mAh cell, the BM6000 a 650mAh one. In real terms:
- Light to moderate vapers: the Hayati usually stretches to two days between charges; the Lost Mary lands at about a day and a half.
- Heavy vapers: the Hayati typically needs a nightly charge; the Lost Mary may need a top-up by early evening.
Both charge over USB-C and both have a small screen showing battery level, so you never get the classic dead-vape-with-full-pod surprise. Neither includes a cable in the box. If you vape hard all day, the 850mAh cell alone is a reason to lean Hayati.
Flavour: Lost Mary's home turf
Hayati sells breadth, Lost Mary sells punch. The Pro Max Plus ships in 60 to 70 plus flavours, covering fruit, ice, menthol, candy, and drinks profiles. They are smooth, consistent, and steady from first puff to last, which is what the dual mesh coil is tuned for.
The BM6000 has a tighter menu, roughly 30 to 55 flavours depending on the retailer, but they hit harder. The QUAQ mesh coil runs slightly hotter and more aggressive, so fruit flavours taste brighter and bolder on the first draw. If your priority is "tastes like the disposable I used to buy," the Lost Mary side wins.
For context on how the two brands' styles usually split, our Elf Bar vs Lost Mary breakdown covers a similar flavour-first versus balanced trade-off.
One practical note: because the BM6000 is a one-flavour-per-kit device and the Pro Max Plus is a one-flavour-per-pod device, neither lets you swap flavours mid-kit without waste. If you like variety across a day, that is a point in favour of multi-flavour kits elsewhere in the best disposables guide.
Puff counts: what 6,000 really means
Both brands advertise "up to 6,000 puffs." That number assumes short 1 to 2 second draws. Real-world testing consistently lands between 4,500 and 5,800 puffs depending on draw length. In everyday terms:
| Vaping style | Rough lifespan, either kit |
|---|---|
| Light (weekend/social) | 2 to 3 weeks |
| Moderate (regular through the day) | 7 to 10 days |
| Heavy (constant use) | 4 to 6 days |
Neither kit will actually outlast the other on liquid alone, since both hold 12ml. The puff gap comes from battery efficiency and how hard you draw, not from the bottle size. Treat "6,000 puffs" as a ceiling, not a promise.
The price math nobody on the shelf does
Kit prices vary by shop, but the typical UK range is £7.99 to £9.99 for the Pro Max Plus kit and £10.99 to £12.99 for the BM6000. Both claim 6,000 puffs:
| Hayati Pro Max Plus | Lost Mary BM6000 | |
|---|---|---|
| Typical kit price | £7.99 | £12.99 |
| Puffs claimed | 6,000 | 6,000 |
| Cost per puff (claimed) | 0.13p | 0.22p |
| Ongoing cost | £5.49 per replacement pod | New kit each time (£12.99) |
| Battery | Reused indefinitely | Replaced with kit |
The ongoing cost is where the real gap opens. After the first kit, Hayati users buy pods at roughly £5.49 and keep the same device and battery. Lost Mary users buy a whole new BM6000 kit each cycle, battery included. Over three cycles, the Hayati route costs about £19 versus about £39 for Lost Mary. If you vape every day, that difference is not trivial.
Design, size, and daily handling
The Pro Max Plus is the taller, slimmer one: a pen-style body around 125mm long and roughly 85 to 93g. It disappears into a pocket and feels closer to a classic vape pen.
The BM6000 is a short, wide box. Slightly lighter at around 75g and more comfortable to palm, but a touch wider in a jeans pocket. Its transparent liquid window is genuinely useful: you can see the pod level drop and know when the reservoir is running dry. The Hayati pod is also translucent, so both keep you informed, but Lost Mary's window is the clearer of the two.
Neither has buttons, airflow adjustment, or settings. Draw, vape, done. If you are new to this style of device and want to understand exactly what it is, our explainer on what disposable means covers how these refill systems differ from old single-use vapes.

| Overall | Value and endurance | Flavour and design | Draw |
Five rounds to Lost Mary, four to Hayati, and the score flatters nobody, because the categories that matter most are personal. A heavy vaper should weigh the battery and cost rounds double. A flavour chaser should weigh the coil and intensity rounds double.
