I'm not a veteran vapor, have used blucig, volcano and the one I'm using now ego with a Korean clearomizer. My biggest point of confusion was the incredibly lengthy threads on this forum. On the plus side it means there is an active, supportive community out there, but for the newb (me) it was way to much to digest at once.
My advice, don't use a cigarette lookalike, the battery life sucks (hehe) and the carts are so little it gets irritating FAST to refill or replace them.
Don't get intimidated by all the different types of ecigs out there, get an ecig with a 510 connector and big battery with 3.7v and branch out from there. Or do what I wish I could have done and get a Reo, I still wanna get one, need to convince the wife I need one... Why can't he sell the batts and attys all together???
Right now I have an EGO, two 900mah, 3.7v batteries, 3 clearomizers (which, while very convenient, crack easily, didn't know this was a common problem) and 3 bottles of 10ml juice which I'm very happy with, for a half a pack smoker this will easily last me a month or more, with the juice running out first.
