I swore up and down that mine was sick, as it would randomly stop recording and freeze up quite often. Eventually I realized that one of my two microSD cards (both identical and purchased together) was bad. I've replaced it, and the camera has been rock solid. Not saying that you didn't have a lemon (or two), but at the data rates the H3BE cranks out, the microSD card has got to be rock solid. One of mine wasn't.
