I have one of these cameras...and have had issues with it from the start. Right now it's on it's way to the manufacturer for warranty (I hope). Mine wont stay on. Shuts off all the time. The company wants to make it about the battery. But, I've tried all kinds of batteries. Nimh's and brand new alkalines. Sure, I know the best is LiPo...but this thing will shut off in under a minute. Hardly a battery issue. Very frustrating too. I've got a couple friends that are happy with theirs. But they are quite a bit more sedate with their cameras. I've put mine on my kneeboard and flipped with it, put it on my sky ski and flew around with it, flipped it, crashed it hard....mounted it on my helmet for mountain trail rides, and most recently....mounted it on my ice bike. It's always been sketchy at best, but at this point it wont stay on.
It's been a real source of frustration. Everytime I've used it (except the first) I sit down to the computer and wonder "how much (if any) did it capture this time". Hopefully, they'll repair it or replace it. I just don't have much faith in that camera right now. Starting to look at the more expensive alternatives.
