I just got my second GoPro as a Christmas gift. I never would have bought a second one, myself, after a year or so experience with the first one. Lousy camera. It's a gimmick. The only thing they did right was come out with all the ways to mount it to things.
Main problem we have with them are that they fog up if you seal them up in their water tight housings for use on boats and swimming. And the little paper dessicant packs are useless.
The other problem with them, of course, is the horrible quality of the images.
