Ever since I switched to the evo I've been having some problems with using it inside of a club with loud music, since I work for a promotions company this is very difficult. It seems the batteries are so sensitive they go off with the slightest thud from a subwoofer and then the batteries simply cut off for a few hours before working again. My crappy e-cig from SE doesn't have this problem, but I honestly would rather smoke an analog than use that thing...anybody have any suggestions?
