My patience with battery doors has become very thin. For Lost Vape, this should be an embarrassment, I expect more for that price point. Even worse, my dual 21700 Rebel door has been so loose from the day I got it that I can't even stand to use it. I don't want to be a negative Nelly here, just stating my personal experiences. I wouldn't be as upset if these were sub $100 mods. Is it really that hard to come up with a design of magnets or clips that keep doors from popping off?
