I bought this version in mid-January after selling my GoPro 2 to a friend. Right out of the box it had issues, even after updating the firmware. Freezes, poor battery life with conservative settings, will not transfer files via the USB cable on a Windows 7 PC, having to do hard resets often. This version should not have been released.

Had horrible, disgusting tonsil stones. This is the first product I found that really helps. I saw other reviews that warned of a bad metallic taste in their mouth so I was a little cautious at first but at least for myself I never experienced any problems with that.
