The ET-S Glass version BDC is an upgrade version of ET BDC, it has an exterior metal sleeve surrounding the tank with two small windows that allow you to see how much liquid is left in the tank at all times.
It is a clearomizer made of glass and metal. These types of clearomizers are commonly refferred to as “Glassomizers” (a clearomizer but with glass walls).
The ET-S holds 3.0ml liquid and has a 1.8 coil inside, 2 windows , 1 either side to see the liquid level.
The tank can be disassembled into four total parts for easy cleaning and maintenance, and the coil head can easily be replaced.
The coils must be soaked in eliquid for 20 mins before using the clearomizer
