For the first 3500 puffs, Mesh A and Mesh B(look at the picture below)of the Duo Mesh rotate each other every 10 puffs. As the coils are still pretty new, each mesh coil can produce a pure flavor. For the last 3500 puffs, as both coils are halfway used, Mesh A and Mesh B work together to produce the same pure flavor as before. That is the reason why we say Friobar DB7000 is the world’s first disposable device with consistent flavor throughout the whole life of 7000 puffs, the last vape is exactly the same as the first vape.
