Summary: Unit kept failing. Didn't hold a charge and overall. Would freeze. Removed battery. Upgraded firmware to no avail. Sent unit back. Buyer beware. Go Pro makes great ads and promo videos, but their quality is poor.
Summary: The GoPro I received froze up frequently which was very frustrating when I was skiing since I had to remove the battery every time this happened. It was entirely unreliable so I returned it to amazon and got a full refund. I haven't decided whether or not I will buy another one.
