Tanks IconTanks or clearomizers are probably the most popular type of atomizer out there and this is because they are intended for all categories of vapers, from the very beginners to veterans with years of experience in the field. They are easy to refill and operate and their simplicity consists in the fact that they work with pre-build, separately sold coil heads. These coil heads screw onto the base and once they give off a burnt taste or don’t produce enough vapor they can be easily swapped.
