@Vapeyourlungsout I'm sure Vaporesso are well aware of the airlock issue... it's been a problem from the first cCell released. It's not just related to ceramic coils (although it seems to be worst with ceramics) and it's a problem that plagued me with most of the tanks with commercial coils... some people never have the problem... but it has driven me to give up on tanks with commercial coils and now pretty much only use RTA's now. Asking for a video is just a load of crap... I'm going out on a limb here and saying you are not the first person on the planet to have the issue! Why the hell they don't just come out and say they are aware of the issue and tell you to loosen the top fill cap... Same story with thier crap cCells they came out with... they never admitted producing a really bad batch of cCells. Such a pity because Vaporesso have real potential and some really great products but they dodge issues and don't reply to emails when they know they have to admit an issue exists!
