Been using ecigs for 2 years, went back to analogs for about 4 months because of letting ecigs get bad- not changing and sterilizing them, so I got bad throat infection, and I was done, but then realized uhh stupid, u got to keep up on this and not let it go for so many months that it creates bacteria.... so now back on for many months, never better, got cartomizers and all, those cool for deep strong hits, regular 510 attys for regular hits, it works well, never want an analog, they are ruined by the ecig really, throat hit not the same, feeling not the same, it's just inhailing dirt as far as im concerned, I try sometimes and just can't. It's amazing how Ecigs can change us off of regular cigs so quick and effective, so amazing, and I feel sorry for all those people who don't get on it... they refuse it thinking it's lesser... and some think they know so much about it, yet don't use it, they have been screwwed by malls and all the crap selling out there, sad...
