I've always used the regular ecig with disposable cartomizers. I just recently bought the Evapor kit from Smoke Free. This came with 2 tanks, one of which I am able to pull apart, the other not. I am assuming by what I've seen that this one can be reused with new guts, only I don't have a clue about these tanks. They tell you nothing about this, they'd rather you buy more tanks at around 42 bucks a hit. I'm betting there are other brand tanks I can buy and use with these batteries, I've seen them online for dirt cheap. If anyone is familiar with this brand or their equipment I would be forever grateful for any tips. I have no knowledge of tanks or their anatomy, all I know is I'm tired of getting my wallet sucked dry for lack of knowledge. Haven't touched a real cig in 2 years..
