so... i have been vaping for about two years now (back when hardly anyone had heard of it). I got my first ecig from ebay back when ebay had ecigs. A geek friend of mine (who did not smoke) got it as a "neat doodad thingy" as he is into the new fun gadgets. I got one too, also as a "neat doodad thingy". I had already quit my tenuous smoking habit a couple years previous to this and got it just for the novelty. Well, this model was a peace of crap and i hardly used it. Eventually (about a year ago) i decided to invest in a better model. I got the two peace 8mm or whatever model from a chinese website. Shipping cost an arm and a leg and half the batteries i got didn't work at all. At this point ecigs have become a hobby and i got the M401 dragon from TrueSmoker. Finally! a product i liked. I stuck with that for a while... Got a Prodigy for my boyfriend (who also did not smoke) as he wanted something that could double as a weapon. Decided i liked manuals. Got the Joye 510 which is my favorite and i am sticking to it (for now).
