Summary: I bought this camera for a xmas gift and had it gift wrapped by Amazon - upon gift being received it had appeared that the GoPro packaging had been opened before due to the poor taping job and assembly which meant that it likely wasn't factory new. Got the SD card later and it wouldn't snap into place as it should, as it appears the internals are damaged - spring in SD port was popped out (which is likely why it was repackaged and sold again).
Summary: I ordered it by mistake while I wanted GoPro Hero 2. Tried to contact the seller for a return, but no response at all. The product seemed also defective in that the recorded video was too dark indoors.
Summary: Got a Hero 2 for Christmas and it just kept freezing up on me. I used a high quality SD card that I use in my SLR camera so that should not have been an issue. Upon further investigation, I learned that there were A LOT of people having this same issue. The GoPro support website had crashed Christmas morning probably due to high traffic. I tried to upload previous firmware versions and this did nothing to help the problem.
Summary: I bought this camera to use on off-road single track rides and adventure races. It worked once on my road bicycle commute,but has not worked since then. Customer support has suggested changing battery types without any difference in performance. It just will not stay on in a bumpy environment. If you buy this camera hang on to your warranty and purchase documents do you can send it back.
Summary: I tried the camera the night before for a test run. Worked fine, but by time I got to the beach the next day, it wouldn't turn on. I tried all the suggestions and it never turned on again. There is a lot of discussions about this same problem. It seems a large percentage of their cameras are just faulty. Very very disappointing.
