Hey, I figured I would get the opinions of you guys out here that have and use one of these cameras. I have the hero2 and was looking into buying a 3, but some of the reviews (quite a bit actually) have not been so pleasant towards the 3 black edition. Most say it is very glitchy and freezes up, and also has horrible battery life (45 min on regular, and 1:15 with the backpack). Has anyone experienced this at all? And anyone out here with one use it for diving/snorkeling? I would like to see actual vids from actual people not professionally edited so I can gauge if I really want to dump the $400 or not. I would consider trading for one though, and will post a thread for that, but only if the opinions are favorable. Otherwise a 2nd hero 2 may be in line.
