I have a 3 piece veppo ecig. automatic. Never heard of it on this forum yet. I hear crackling sounds. What kind of alcohol do I use to clean it if this is the case? Or are there other methods? Its my first ecig kit which I paid way too much for. Its a hassle refilling all the time. I started using marineland blue foam rite size u and it seems to work good. But I think I stuffed it too much. I've watched the videos but just not so clear on the filler size. ITs dinky, does'nt hold much juice. th good but medium vapor which I would like more of. Looking for alterative in near futhur. Anyway, need to do something about cleaning it. Sometimes I have to really give it a good suck to get anything out of it even when it is full.
