Sorry I dont understand all the abbreviations here yet. . Getting alot of great help . OK, Is the Ego another type ecig or what? I am alittle confused about this. If I get the Joye from Cignot or if I get the Ego from there too, I am in good shape? I would like a longer battery life. Guess I want to know the best package to get that has most of what i need in it. In order words,I need to start simple with this thing so I dont spend too much and am in the same shape I am in now. Dont mind spending another $100 right off if I need to. But I dont understand about the different batteries and what a passthrough is...Again I do appreciate you taking time to help me.
