Lost Mary BM6000 vs Hayati Pro Ultra 25K: Which Is Better Value?
Both the Lost Mary BM6000 and the Hayati Pro Ultra Plus 25K are hugely popular in the UK right now - but they are designed for completely different types of vapers. One is a compact, single-use-style pod device that delivers 6,000 puffs at a low upfront price. The other is a rechargeable kit offering 25,000 puffs, a dual-flavour system, and an LCD display. Choosing between them comes down to how much you vape, what you value, and whether price per puff matters to you.
This comparison covers every metric that matters: puff count, cost per puff, flavour range, technology features, battery life, and post-ban compliance. By the end, you will know exactly which device suits your needs.

Quick Verdict at a Glance
If you want the summary before the detail, here it is. The Hayati 25K wins on every metric that matters to moderate or heavy vapers. The Lost Mary BM6000 is the better choice only for very light users who vape occasionally and prefer a lower upfront spend.
| Feature | Lost Mary BM6000 | Hayati Pro Ultra 25K |
|---|---|---|
| Puffs per device | 6,000 | 25,000 |
| Price | ~£8.99-£10.99 | £10.99 (2 for £18) |
| Cost per 100 puffs | ~£0.18 | £0.044 |
| Flavours per device | 1 | 2 simultaneously |
| LCD display | No | Yes - puff count + battery |
| Rechargeable | Yes (USB-C) | Yes (USB-C fast charge) |
| Post-June 2025 compliant | Yes | Yes |
| Prefilled pods | Yes | Yes - dual pods |
Puff Count Comparison
This is the starkest difference between the two devices. The Lost Mary BM6000 delivers 6,000 puffs - a solid number for a pod-style device and a meaningful upgrade from 600-puff bars. But the Hayati Pro Ultra Plus 25K delivers 25,000 puffs: more than four times as many per device.
What does that mean in real terms? A moderate vaper taking 300 puffs per day will get through a Lost Mary BM6000 in roughly 20 days. The same person would get approximately 83 days from a single Hayati 25K - nearly three months from one purchase. A heavy vaper taking 500 puffs per day exhausts the Lost Mary in 12 days. The Hayati lasts around 50 days at the same pace.
More puffs per device also means less frequent purchasing, less packaging waste, and fewer trips to the vape shop. For regular vapers, the Hayati 25K's longevity is not just convenient - it is genuinely cost-saving.
Cost Per Puff Breakdown
The Lost Mary BM6000 typically retails between £8.99 and £10.99 for a single device. At £9.99 for 6,000 puffs, the cost per 100 puffs is approximately £0.17. The Hayati Pro Ultra Plus 25K retails at £10.99, or £9.00 each on the 2-for-£18 deal. At £10.99 for 25,000 puffs, the cost per 100 puffs is £0.044.
That means the Hayati 25K delivers puffs at roughly four times lower cost than the Lost Mary BM6000 on a like-for-like basis. Over a full year, a moderate vaper (300 puffs/day) would spend approximately:
- Lost Mary BM6000: around 18 devices per year at £9.99 = roughly £180
- Hayati 25K: around 4-5 devices per year at £10.99 = roughly £49
Annual saving with the Hayati: over £130. For heavy vapers the saving is proportionally larger. The higher upfront price of the Hayati 25K pays for itself within weeks.
Flavour Range
Both devices offer a broad flavour range. The Lost Mary BM6000 is available in a wide selection of fruit, menthol, and candy flavours - popular choices include Blue Razz Ice, Watermelon Ice, and Kiwi Passion Fruit Guava. Each device comes pre-filled with a single flavour, which you stick with until the device is finished.
The Hayati Pro Ultra Plus 25K is available in over 30 flavours across both single-flavour options and dual-flavour pod combinations. The full Hayati flavour range includes Berry, Tropical, Menthol/Ice, and Sweet/Candy categories - comparable depth to Lost Mary.
The key difference: with the Hayati 25K, dual-flavour pods let you carry two flavours in one device and switch between them instantly. You are not locked into a single flavour for 25,000 puffs.
The Dual-Flavour Advantage
This is where the Hayati Pro Ultra 25K pulls away from every competitor, including the Lost Mary BM6000. The Hayati uses a twist mouthpiece system: load two different flavour pods into the device, then twist the mouthpiece left or right to switch between them instantly - no swapping pods, no carrying two devices.
Popular dual-flavour combinations available at UK Vape World include:
- Watermelon Bubblegum / Strawberry Bubblegum
- Blueberry Cotton K / Raspberry Cotton K
- Grape Gummy Bear / Strawberry Gummy Bear
- Straw Grapefruit / Straw Dragonfruit
- Kiwi Banana / Straw Banana
The Lost Mary BM6000 offers no equivalent. When you pick a flavour at purchase, that is what you vape until the device is done. For vapers who like variety throughout the day, the Hayati's twist system is a genuine quality-of-life upgrade.
LCD Display and Smart Features
The Hayati Pro Ultra Plus 25K includes a real-time LCD display showing your current puff count and remaining battery level. You always know exactly how much is left and when to charge. The intelligent chip set also includes an active flavour indicator so you know which pod position is active.
The Lost Mary BM6000 has no display. You have no way of knowing how many puffs remain or how charged the battery is until performance starts to drop. For a device you use daily for weeks, that lack of visibility is a genuine inconvenience.
Battery and Charging
Both devices use USB-C charging. The Lost Mary BM6000 has a 600mAh battery, sufficient for the device's 6,000 puff lifespan. The Hayati Pro Ultra Plus 25K uses an 850mAh battery with fast charging - fully charged in under one hour. Given the 25,000 puff lifespan, you will charge the Hayati far less frequently than you replace the Lost Mary.
Post-Ban Compliance
Both the Lost Mary BM6000 and the Hayati 25K are compliant with UK vaping regulations. Both are rechargeable prefilled pod kits rather than single-use disposables, meaning both remain legal following the June 2025 single-use vape ban. If you were using older 600-puff single-use bars and switched to the BM6000 or the Hayati 25K, your device is already compliant.
Who Should Choose the Lost Mary BM6000
The Lost Mary BM6000 is the right choice if:
- You are a very light vaper who uses fewer than 100 puffs per day - the cost difference over a year becomes less significant
- You want a smaller, more pocketable device - the BM6000 is slimmer and lighter
- You prefer no ongoing pod purchases - the BM6000 is self-contained, no separate replacement pods to track
- You are new to vaping and want a simple, low-commitment entry point before investing in a larger kit
Who Should Choose the Hayati Pro Ultra 25K
The Hayati Pro Ultra Plus 25K is the right choice if:
- You are a moderate to heavy vaper (200+ puffs per day) - the cost per puff saving is substantial
- You want two flavours in one device - the twist system is unique to the Hayati
- You value knowing what is left - the LCD display shows puff count and battery in real time
- You are switching from cigarettes - the 20mg nicotine salt and MTL draw closely mimic a cigarette
- You want to buy less frequently - one Hayati device lasts the equivalent of 4+ Lost Mary BM6000 devices
Final Verdict
Our Verdict
For most UK vapers, the Hayati Pro Ultra Plus 25K is the better buy. The cost per puff is four times lower, the dual-flavour twist system is unique on the market, and the LCD display removes all guesswork. At £10.99 - or £9.00 each on the 2-for-£18 deal - it is only marginally more expensive upfront than a Lost Mary BM6000 but delivers dramatically more value over its lifetime.
The Lost Mary BM6000 remains a solid choice for light users who want simplicity and a smaller device. But for anyone vaping regularly, the Hayati 25K pays for itself within weeks and offers a noticeably better experience.

Frequently Asked Questions
Is the Lost Mary BM6000 the same as the Lost Mary BM600?
No. The Lost Mary BM600 is an older 600-puff single-use bar that is now banned in the UK. The BM6000 is a rechargeable prefilled pod device delivering 6,000 puffs - it is a different, larger, and compliant product.
How many Lost Mary BM6000 devices equal one Hayati 25K?
Approximately four to five. The Hayati delivers 25,000 puffs versus 6,000 for the BM6000. You would need around four BM6000 devices to match one Hayati 25K at a total cost of roughly £36-£44 versus £10.99 for the Hayati.
Can I buy Lost Mary BM6000 replacement pods?
The Lost Mary BM6000 uses its own proprietary pods. UK Vape World stocks Lost Mary BM products including box-of-10 multipacks in popular flavours.
Does the Hayati 25K use the same pods as Lost Mary?
No. The Hayati 25K uses its own Hayati Pro Ultra Plus prefilled pods, available in over 30 flavour options. The two systems are not compatible with each other.
Which is better for heavy smokers switching to vaping?
The Hayati Pro Ultra Plus 25K. It delivers 20mg nicotine salt via a mouth-to-lung draw that closely mimics a cigarette, provides enough puffs to last weeks between purchases, and the LCD display gives reassurance about remaining charge and puffs. The cost saving versus buying multiple Lost Mary devices is also significant for daily users.
Are Lost Mary BM6000 flavours available at UK Vape World?
Yes. UK Vape World stocks Lost Mary BM products including Blue Razz Ice, Watermelon Ice, and Kiwi Passion Fruit Guava in box-of-10 multipacks for better value per unit.
Is the Hayati 25K harder to use than a Lost Mary?
No. The Hayati 25K is draw-activated just like the Lost Mary - no buttons, no settings. The only additional step is loading the prefilled pods when you first set up the device or when replacing them. UK Vape World's how to use the Hayati 25K guide covers setup in detail.
