cinera

I've had the thing for a week. Regular usage. Now it gives out the faintest hint of a puff. But nothing more. Wtf should I do? I had the ePuffer Classic (penstyle) and it sucked just as bad as this one. This was the replacement. Should I try to send this one back too?? Kjflkdfjlsdkfjkld and what happened to e-cigarette-forum????
