Been sitting there absent mindedly been vaiping away and all of a sudden get a really horribly bad, burned hit? Like 5 times in a row it happened to me, plus my provari kept maxing out at 6 volts, it was POSSESSED! Then I realized that I had been hitting the button enough times while chain vaping to get into the PU screen and maxing it out. I was literally ready to hit send on a panicky S.O.S email to Provape when I realized what I had been doing. So I won't be designing any rockets any time soon.
