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!
