Lost Mary BM600 vs. Lost Mary QM600: What’s the Difference?

Lost Mary has long been established as a leading, or arguably the leading brand in the disposable vape market, renowned for its commitment to bold flavour, user-friendly designs, and high-performance devices.

Among their popular offerings, the Lost Mary BM600 and QM600 stand out, and have become the go-to devices for vapers seeking convenience, portability, and a satisfying nicotine experience. While both models share similarities in size, nicotine strength, and puff count, they differ significantly in regards to their design, flavour delivery, throat hit, and more.

In this article, we give you a comprehensive breakdown of these key differences, so you can make a more informed decision about which of these two great little disposable vapes is right for you.

Unboxing and First Impressions

Both the Lost Mary BM600 and QM600 come in slim, compact packaging with clear flavour labeling. As anyone who has used disposable vapes before will know, neither device requires assembly or charging; they simply need to be removed from their packaging to begin vaping.

The Lost Mary BM600 features an ergonomic, bottle-shaped design, providing a smooth and comfortable grip. It is immediately clear that its shape has been designed for portability, making it ideal for on-the-go vaping. The Lost Mary QM600 showcases a more angular, box-like form with a dual-tone metallic aesthetic encased in a transparent outer shell. While different from the BM600, its design is arguably more visually striking.

Design and Build Quality

Let’s get a bit more granular about the key differences in form between these two devices.

The Lost Mary BM600’s compact, pebble-like form ensures that the device sits comfortably in the hand, and its soft-touch coating provides a non-slip grip, making it easy to hold during extended vaping sessions. The branding is minimalistic, and the pastel-like colour gradient, which varies depending on the flavour, adds a touch of style without being overly flashy. At 66mm in height and 16mm in width, you can slip it into your pocket with ease. Equipped with a small, tapered mouthpiece that delivers a restricted draw, the device closely emulates the sensation of a traditional cigarette.

Conversely, the Lost Mary QM600 features a glossy, transparent casing that reveals a striking metallic dual-tone gradient beneath, giving it a slightly more premium feel compared to the BM600. Due to its elongated, rectangular shape design, it’s longer than the BM600, with a height of 96.7mm and a width of 14.2m.

Despite the different materials and finishes, both devices are equally lightweight and portable, ensuring effortless pocket or bag carry. The QM600’s harder plastic build provides a sturdier feel, while the BM600’s softer, matte finish may be preferred for enhanced comfort.

Flavour and Vapour Production

Of course, all of the aspects we are analysing and comparing between the two devices in this guide are important, but when it comes to choosing a disposable vape, realistically, what could be more important than the flavours available? For many vapers, flavour is the deciding factor with any vape purchase, turning a simple nicotine delivery device into an enjoyable experience.

The Lost Mary BM600 provides a smooth, satisfying draw with well-balanced flavour intensity. It produces a moderate amount of vapour, suitable for discreet vaping. It features 35 flavours, focusing on bold, sweet, and fruity blends. Its deep, intense flavours cater to those who enjoy punchy, sweet fruit mixes.

Now, when it comes to quality of performance, there’s an important difference found in the QM600 that may influence your decision: a mesh coil. The debate over which is the better option between mesh coils or traditional coils has been long-standing, with mesh coils being found most often in sub-ohm devices. In these kits, mesh designs help to create even bigger clouds of vapour as they can heat up more e-liquid more efficiently.

However, in recent times, manufacturers have been increasingly using mesh coils in lower-powered pod kits, in order to help provide extra flavour, as well as vapour. This technology, combined with a slightly more refined airflow system, results not only in increased vapour production, but a denser and more flavourful inhale also, making each flavour taste sharper and more defined. While also offering over 30 flavours, the QM600's lineup includes more beverage-inspired and icy options, with a focus on smoother blends and cleaner, well-balanced fruit profiles.

The BM600 features a slightly tighter draw of the two devices, mimicking a traditional cigarette, while the QM600 offers a slightly airier draw, largely due to its slightly wider mouthpiece.

Nicotine Strengths and Throat Hit

Both the BM600 and the QM600 use 20mg nicotine salt, providing a satisfying nicotine hit without the harshness associated with freebase nicotine. While both offer a smooth throat hit, subtle differences exist. The Lost Mary BM600 delivers a slightly stronger throat hit of the two, due to its airflow design and coil setup. If you prefer a more pronounced, cigarette-like sensation with each puff, this is the device for you.

Conversely, the Lost Mary QM600, with its organic cotton wick and mesh coil system, delivers a smoother and more refined experience. Its throat hit is a touch smoother, making it the more preferable option for vapers who favor a more mellow inhale.

Ultimately, both devices cater to mouth-to-lung (MTL) vapers. Despite their minor differences in throat hits, both deliver very satisfying nicotine experiences.

Battery Life and Performance

Both the Lost Mary BM600 and QM600 are designed as pre-filled disposable vapes, each rated for approximately 600 puffs, aligning with industry standards. As is common with disposable vapes, the actual puff count can vary depending on individual usage habits, such as puff duration and frequency. If users can generally expect around 600 puffs from each device, this typically translates to 3-4 days of use for an average vaper.

Both the Lost Mary BM600 and QM600 feature a 350mAh built-in battery. While this battery capacity is designed to last for the duration of the pre-filled e-liquid, ensuring consistent performance, it's essential to remember that 350mAh indicates the battery's capacity. Individual usage patterns will still influence the actual lifespan of the device.

Ease of Use and Convenience

Both the Lost Mary BM600 and QM600 have been created with maximum ease of use and convenience in mind, making them perfect for all vapers, regardless of experience level. Being draw-activated, neither uses any buttons or complex settings - a hassle-free vaping experience is guaranteed, making these devices perfect for use when out and about.

Both offer instant activation with no noticeable lag, providing immediate satisfaction. Despite their ease of use, both come with a user manual, providing basic guidance for first-time users.

Neither device experiences significant leakage issues, and both are designed to withstand everyday use. However, the QM600's harder plastic shell provides slightly enhanced durability, making it more resistant to damage from accidental drops.
