The EVOD clearomizer has an eGo style fitting with a replaceable bottom coil, transparent tank covered by a metal protective cover. These clearomizers hold around 1.6ml of liquid. The clearomizer uses bottom coil technology to produce a huge amount of vapour, throat hit and flavour. The bottom coil mechanism ensures the wick is fed constantly as you vape away making gravity push the liquid to channel through to the coils in a super efficient manner. You will also have no leaking issues with this tank if you keep hold of all the seals and O rings that come fitted in the tank. The sheer simplicity of using and maintaining this device makes it an ideal kit for both starter and advanced users equally.
