Well.. I do not own a battery charger since the one i had got really hot and stopped working a few months ago. Im thinking of buying a new one but i anyways dont think i should be ok with a "quality" mod breaking and loose one of it's most vital functions after just 10 days usage. I have some older isticks with fixed batteries and other mods with usb port and all of them still have a functioning usb-port. Its easy to be disappointed when something you thought was great and waited a month for broke more or less when you got it.
