Ok, I couldn't wait....I wanted to get an ecigg NOW, lol. I got one at the Tobbacco Store.....Mystic NicStick. I got 3 tank cartriddges, USB charger, and one automatic battery...whick I like more than the button one (tried one earlier). My question is can I mix brands of cartomizers, tank (holds the eliquid), batteries, ect?
