IVG Pro 12 vs Lost Mary BM6000: Which Wins?
Two of the most talked about prefilled pod kits in the UK, compared on puffs, cost, flavour, feel and convenience, so you can pick with confidence.
The IVG Pro 12 and the Lost Mary BM6000 are two of the best known prefilled pod kits in the UK. Both arrived as compliant, rechargeable replacements for the disposables that are no longer sold, and both aim to give you that same easy experience with far less waste. They look similar on paper, so the right choice comes down to a handful of practical differences. This guide lays them out.
Specifications shift as ranges are updated, so always check the current product listing before buying, but the broad picture below has held steady and gives you a clear basis for comparison.

Side by side
| Feature | IVG Pro 12 | Lost Mary BM6000 |
|---|---|---|
| Puff count | Up to 10,000 | Up to 6,000 |
| Liquid system | 2ml pod plus 10ml refill (around 12ml) | 2ml pod plus refill container |
| Nicotine | 20mg nic salt | 20mg nic salt |
| Charging | USB-C, 1000mAh | USB-C, rechargeable |
| Activation | Draw-activated | Draw-activated |
| Inhale style | Mouth-to-lung | Mouth-to-lung |
| Coil | Mesh | Mesh |
The headline gap is simple: the Pro 12 carries a higher rated puff count from a larger total liquid capacity. Everything else is broadly comparable, which is why this decision usually comes down to longevity, value and flavour preference rather than raw features.
Puffs and value
On paper the Pro 12 lasts longer per kit, with up to 10,000 puffs against the BM6000's 6,000. In practical terms, that usually means fewer purchases over a month and a lower cost per puff, assuming the kits are similarly priced. If you vape regularly, that difference adds up over time and the Pro 12 tends to be the cheaper habit to maintain.
If you vape only lightly, or you like to switch flavours often, the gap matters less. A 6,000 puff kit may be finished at a comfortable pace before you tire of the flavour, and the lower capacity is not a drawback. Think about how you actually vape, not just the bigger number.
Flavour
Both brands are known for strong, well made flavours, and this is the most personal part of the decision. IVG leans into bold fruit, ice and sweet soda profiles, with a range that includes reliable all-day options like Strawberry Watermelon alongside sweeter treats. Lost Mary has its own signature blends with a loyal following. Neither is objectively better; it depends entirely on your palate. The only real way to settle it is to try a couple from each brand. Our ranked Pro 12 flavour guide is a good place to start narrowing down the IVG side.
Feel and everyday use
Day to day, the two devices are very close. Both are button-free, both recharge over USB-C, and both give a tight mouth-to-lung draw. The Pro 12's mesh coil and auto-feeding refill are designed to keep flavour even across a longer kit life, which is the experience many heavier users care about most, since it avoids the gradual fade some devices suffer toward the end. Build quality, pocket feel and the position of the LED indicator are personal preferences you can only judge by handling each one.
Which should you pick?
- Choose the IVG Pro 12 if you want the longest life per kit and the best cost per puff, you vape regularly, and you like IVG flavours.
- Choose the Lost Mary BM6000 if you already prefer Lost Mary flavours, you vape more lightly, and a 6,000 puff kit comfortably covers your usage.
For sheer longevity and value, the Pro 12 usually edges it thanks to its higher capacity. For flavour loyalty, go with whichever brand you already enjoy, because both are well made and the flavour is what you live with every day.
Capacity and what it means for you
The clearest difference between the two kits is capacity. The Pro 12 is rated up to 10,000 puffs, the BM6000 up to 6,000. In day-to-day terms, the Pro 12 will typically go longer between purchases, which suits heavier or regular users who do not want to keep rebuying. For a lighter user, a 6,000 puff kit may be plenty and may even be finished at a comfortable pace before the flavour starts to feel familiar. The bigger number is not automatically better; it is better for people who vape enough to benefit from it.
Cost per puff, worked through
Value is best judged on cost per puff rather than the price on the shelf. If two kits cost a similar amount but one delivers 10,000 puffs and the other 6,000, the higher-capacity kit is cheaper for every puff you take. Over a month of regular vaping that gap compounds into a meaningful saving. The exact figures depend on current pricing, so check the latest, but the principle holds: for regular users, the Pro 12's higher capacity usually makes it the more economical habit.
Flavour range and feel
Both brands have strong, loyal followings, and flavour is ultimately personal. IVG's Pro 12 range spans balanced fruit all-day options, refreshing ice blends, clean menthol and indulgent sweet sodas, so there is breadth across styles. Lost Mary has its own well-regarded line-up. Rather than trying to declare a winner, the sensible approach is to pick one or two from each brand in the style you like and judge for yourself. If you are exploring the IVG side, our ranked flavour guide and bestseller list are the quickest ways in.
Build and portability
Both devices are compact, pocket-friendly and button-free, and both recharge over USB-C. Differences in exact size, weight, mouthpiece feel and the position of the LED indicator are matters of personal preference that are best judged by handling each. Neither is bulky, and both are designed to slip easily into a pocket or bag for everyday carry.
Verdict by user type
| You are | Better pick | Why |
|---|---|---|
| A regular, all-day vaper | IVG Pro 12 | Higher capacity, lower cost per puff |
| A lighter or occasional vaper | Either | 6,000 puffs is ample; choose on flavour |
| Loyal to Lost Mary flavours | Lost Mary BM6000 | Stick with the flavours you enjoy |
| New and undecided | IVG Pro 12 | Longevity and value reduce the risk |
Two different flavour philosophies
Beyond the numbers, the two brands have slightly different flavour personalities, and that can matter as much as capacity. IVG is known for bold, clearly defined flavours across fruit, ice, menthol and sweet soda, with several balanced all-day options. Lost Mary has cultivated its own signature blends that its fans return to. Neither approach is better; they simply appeal to different palates. If you have enjoyed IVG flavours before, the Pro 12 will likely please you, and if Lost Mary blends are your favourites, that loyalty is a perfectly good reason to choose the BM6000.
Refills and ongoing availability
Whichever you choose, think about the ongoing cost and availability of refills or replacements, not just the starter kit, because that is what you live with over time. The Pro 12 keeps going on genuine IVG refill packs, widely stocked across its flavour range. Factor refill pricing into your comparison, since a kit with a slightly higher upfront cost but cheaper or longer-lasting refills can work out better over a month.
Final thoughts
If you want one recommendation: for regular vapers who value longevity and low cost per puff, the Pro 12's higher capacity usually makes it the smarter buy, and its flavour range is broad enough to suit most tastes. For those already devoted to Lost Mary flavours, or who vape lightly enough that 6,000 puffs is plenty, the BM6000 remains a fine choice. Both are well made; the decision is really about capacity, value and which flavours you love.
