I don't know if it's cause I'm new to this or whatnot, but I have found that I just can't put this thing down! I don't know how much juice I am vaping, but I think I am vaping more than I smoked, and i was a pack a day smoker. Maybe it's cause I can actually vape inside instead of having to go outside for a cigarette. It's cool to cause If im watching TV or something, I don't have to worry about being interrupted over a smoke break LOL.. All comments welcome, thanks.
