Lost Mary BM6000 Review: The King of Big Puffs in 2026

The Lost Mary BM6000 is the device that defined the post disposable era in the UK. Taking everything people loved about the banned BM600 and rebuilding it as a legal rechargeable Big Puff system, it has become the best selling reusable vape of 2026. We tested it for three weeks. Here is the full review.

Design and Build

The BM6000 keeps the iconic boxy shape of the BM600 but slightly larger to fit the rechargeable 650mAh battery and USB-C port. It feels solid, the mouthpiece is comfortable, and the dual tone finishes look premium. It is bigger than a disposable but still pocket friendly. See our brands page for more on Lost Mary.

How It Works

Inside is the 2ml plus 10ml system: a 2ml pod connected to a 10ml auto refill reservoir. You vape, the reservoir tops up the pod automatically, and you get around 6,000 puffs per device. When the liquid runs out, replace the pod unit. The battery recharges in about 45 minutes. Our disposable alternatives guide explains Big Puff tech in detail.

Flavour Quality

This is where the BM6000 wins. The mesh coil delivers flavour that genuinely matches the old BM600. Blue Razz Lemonade, Marybull Ice, and Triple Mango are standouts. Consistency is excellent from first puff to last, with no burnt taste as the pod empties. It sets the benchmark in our best vapes 2026 roundup.

Battery Life

The 650mAh battery lasts most users a full day of heavy vaping. USB-C fast charging means a quick top up at lunch covers the evening. No complaints.

Cost Per Puff

At £12 to £14 per device for 6,000 puffs, the BM6000 costs around £2.20 per 1,000 puffs. The old BM600 cost £10 per 1,000 puffs. That is nearly 5x cheaper. Note the UK vape tax coming in October 2026 will add a little to the price.

Drawbacks

It is not the longest lasting Big Puff device. The Hayati Pro Ultra Plus offers 25,000 puffs for not much more money. And if you want flavour switching, the IVG 2400’s 4 pod system is more fun. But for pure flavour quality, nothing beats it.

Verdict

The Lost Mary BM6000 earns 9/10. The best flavour of any Big Puff device, fair pricing, and dead simple to use. If you miss disposables, this is your device. Read more in our reviews section and check deals for the best price.
