So I quite vaping for quite awhile and have recently just gotten back into it, heavily. I've been really enjoying my Tesla, only all the sudden tonight in the middle of using it. Every time I hit the button it just displays "SHORT". I know it's the Tesla because I've tried all different tanks and clearos, all with the same results. I tried giving the contact where the tanks screw in, but with no change. Anyone have any idea what's wrong and what I can do to fix it? And if it's hopeless can anyone recommend a nice APV with a cheap or at least reasonable price tag? I've been out of the game for awhile, but I guess if there's nothing new that you guys recommend I'll probably just go with another Tesla. Thanks in advance.
