i just really cant decide what to buy .... everyones opinions vary ....ahhhhhhh what to do what to do i think im torn between an eGo or 510 the only thing keeping me from the eGo is its size but it has the better battery charge ...i would really hate to buy the 510 and be happy with it for a month then decide to switch to the eGo ... i have been vaping a little over a week now and i know this is something i enjoy....... just the E-cig i have now sucks.... its a bulldog i purchased from the local head shop to help stop smoking .... any input appreciated!!!
