I've had my k3 for about a month now and its already started acting up. I was in the middle of using it and the light on the button just shut off so I figured it was dead. Well I plugged it in for a couple hours and the light was working and blue on the button but when I went to use it, it didn't even light up. Not really sure where to go from here. Don't exactly want to buy a whole new battery when I practically JUST purchased this one.
