FM COILTECH5.0/Double-D mesh is a closed circle but a traditional mesh of the FM COILTECH4.0 is an unclosed semicircle. That’s the big difference in the structure of the mesh coils. As for the Double-D mesh, the structure of a closed circle is the recipe for a 50% improvement in heating speed and flavors.

Stable structure and maximum heating surface area contribute to even heat distribution, bringing you a more consistent vaping experience.
