Comparing the Crystal 600 Pro and Lost Mary BM600 for Smoothness

A head-to-head comparison of two leading 600-puff disposables on draw smoothness and throat feel.

Quick answer: Both the Crystal 600 Pro and Lost Mary BM600 use 20mg nicotine salt and deliver a smooth MTL draw. The Crystal 600 Pro's mesh coil gives it a slight edge on consistent draw smoothness across the full device life. The Lost Mary BM600 has a slightly more open airflow that some users find softer. Both are considerably smoother than freebase nicotine at equivalent strength.

Smoothness is one of the most frequently cited reasons vapers choose a particular device. Here is a direct comparison of two of the UK's most popular 600-puff disposables on this key dimension.

Smoothness Factors Compared

Factor	Crystal 600 Pro	Lost Mary BM600
Nicotine type	20mg nicotine salt	20mg nicotine salt
Coil type	Mesh coil	Mesh coil (BM600 also uses mesh)
Airflow design	Moderate MTL; slightly tighter draw	Slightly more open MTL; marginally softer resistance
Throat hit at 20mg	Smooth; nic salt formulation minimises harshness	Smooth; similar nic salt formulation
Vapour temperature	Warm, consistent	Slightly cooler on some variants; flavour-dependent
Consistency across device life	Excellent; mesh coil maintains smoothness to end	Good; minor drop-off in final quarter reported by some users
Smoothness on iced variants	Additional menthol cooling reinforces smooth feel	Similar cooling effect on iced variants

What "Smoothness" Actually Measures

When vapers describe a draw as smooth or harsh, they are responding to three things: the physical resistance of the airflow (how hard they have to draw), the throat hit from nicotine (freebase stings at high concentrations; nic salt does not), and the vapour temperature (cooler vapour feels smoother). Both the Crystal 600 Pro and Lost Mary BM600 score well on all three because both use 20mg nic salt with mesh coils. The differences between them are subtle rather than dramatic.

Smoothness comparison: Crystal 600 Pro vs Lost Mary BM600 across four dimensions (out of 10)

Longer bar = smoother on that dimension. Crystal edges ahead on consistency; BM600 slightly softer airflow.

Draw consistency (full device life)

600 Pro: 9.3

Draw consistency (full device life)

BM600: 8.5

Airflow softness (resistance)

600 Pro: 8.2

Airflow softness (resistance)

BM600: 8.8

Throat hit (nic salt smoothness)

Both: ~9.2

Frequently Asked Questions

For draw consistency across the full device life, the Crystal 600 Pro is marginally better due to its mesh coil performance maintaining smoothness into the final quarter. For raw airflow softness (draw resistance), the Lost Mary BM600 is marginally more open. Throat hit from nic salt is effectively equivalent in both. The difference is subtle enough that personal preference for a specific flavour often matters more than any smoothness distinction between the two devices.

No. Crystal 600 Pro uses SKE's proprietary nic salt formulation; Lost Mary BM600 uses ELFBAR's (Shenzhen Weiboli Technology) formulation. Both are benzoic acid-based nic salt systems at 20mg/ml, which is what produces the smooth throat feel. The specific blend ratios differ between manufacturers but the resulting smoothness is very similar.

With single-use disposables banned in the UK, the relevant comparison is Crystal Plus pod kit vs Lost Mary BM6000 rechargeable disposable. The BM6000 delivers 6,000 puffs per sealed device (whole device discarded when liquid runs out). The Crystal Plus delivers approximately 600 puffs per pod with a reusable battery. Both carry the flavour and smoothness character of their respective brand lineages.

Yes. The Lost Mary BM600 is a single-use disposable and is banned from UK sale from June 2025 under the same regulations as the Crystal 600 Pro. Both brands have rechargeable successors available through authorised UK retailers. Celtic Vapours stocks current legal alternatives from both brand families.
