First my e-history, then a question. I started with Cig2o,then 510, 510-t, eGo-t ('A'tank), then the 'b' tank, which leaked & required some kind of wick adjustment(couldn't figure it out), back to the 'a' tank, then I started smoking again. I just bought the eGo-C, with the 'A' tank. & pass-thru. Pretty content,haven't smoked for ovr 48 hours. QUESTION: Is there a product/system that's dependable(no leaking), and is VERY user friendly? I really am hopeless at doing much more than cleaning an atty. The less I have to refill or fuss the better. I vape like I smoked, constantly. Thanks
