Njoy is GARBAGE, and so is that Logic.. You will never be able to quit using that shit.. Your best bet would be to look around for the best deal on an Ego Kit.. If you look at that picture, you'll see one that says "Ego-T" on it.. It's about the size of a cigar, the battery will last you all day without having to recharge.. The ones that look like cigarettes (the one I have with the green tip), those batteries wil only last about an hour of good use, so they suck.. An ego kit with 2 batteries, 2 atomizers and a charger and shit shouldn't cost you more than 50-60 bucks.. The best money you'll ever spend.. Then the hunt for the right flavors of juice.. If you tell me what you are looking for I can tell ya what to get and where to get it..
Also the BEST forum for learning about the shit so you don't go fucking off a bunch of money is
http://www.e-cigarette-forum.com/forum/ they got all kinds of info and video reviews and shit.. Lurk on there for a while before you make any purchases...
