Hi all! What a good day to you! I need some help. I bought the v2cigs electronic cigarette, and you have to suck really hard to get it going, then one of the cartridges which are supposed to last like a pack or 2 of cigarettes gave out in just a few hours. Did you have used the v2 electronic cigarettes the Green Smoke e-cig, Inshare electronic cigarette, blu cigs, Apollo Cig? I want to try another brand and want some other people's opinions. Thanks!
