A big (!!!) problem is the wrist strap: While snorkeling I've found that the ring that connects the loop with the stick, may be loose. Would that I noticed no accident, the stick would have to slip away together Gopro - happens at a stupid place and the camera goes on a dive from which it is not to pick up again. Top right after your purchase the cheap ring exchange by a massive key ring and then you should be on the safe side.
