Sorry but this is hacking me off a bit. Lot of assumptions being made. I haven't seen Your customers bathroom. But I can tell you mine is plenty big enough and has ample gfi protected appropriate counter space to charge on. I don't happen to, but no "warm shower" would have a chance of having any real impact on a charging battery. Great idea? Maybe not. More likely a mass produced Chinese battery failed, as happens TOO often, rare in absolute terms as it may be. I'm glad I'm not your customer, would hate to have my misfortune, near miss with disaster be posted along with my vendor rofl about my lack of common sense and stupidity. It's flipping obnoxious and could have been shared with a good deal more empathy and respect while still making your point. But that's just me. Battery safety and battery quality are serious issues for vaping in general. With so many issues regarding perception and misinformation, it's going to be something like this but worse that really gives vaping the public black eye so many would like it to get. Most incidents so far luckily have been minor, with minor or no injuries. But at the rate these devices proliferate, and the lack of understanding about the potential for harm when batteries and charging are not handled properly, I hate to think of seeing a headline about a house burning down with a family of 5 in it. God forbid anyone rofl'ing then. Sigh, I'll get off my soap box now.
