Got one for Christmas... and I'm having multiple firmware issues. I mounted it on my MTB (the price of the accessories is insane !), started recording (1080p, Superview, 48 fps), after a little over 30 minutes the thing freezes. I have to hold the power button for several second for it to reboot. I can then start recording again. Of course the first 30'ish minutes are missing from the SD card. Same thing happened now two times out of two rides :-| Incredible !
