It worked perfectly, and at first I was pleasantly surprised to find that it came with two extra batteries and a charging cradle, until I realised that the two extra batteries weren't Gopro batteries. They did fit in the camera, but with difficulty, and then it was impossible to get them out properly, so I was forced to use tweezers after breaking the tab provided. Apart from that, I enjoy using it with my friends for all sorts of activities (football, cycling, karting...) in short, all sorts of things, I recommend it.
