at this point i feel quite stupid. Ive already managed to burn out one of my cartos in a matter of a couple days of moderate vaping and after filling two others i cannot manage to make either function in my e-pipe. Im using an XL dual coil cartomizer by smoketech and I've filled it with my 30/70 vg/pg blend e liquid about 20 drops and i cant get any vapor out of either of them. please help.
