I have used one for some time last season. Simple to use and very small and compact. You can get pretty creative with camera angles with some of the included mounts for helmets and chest harness. The chest harness is the way to go as far as never losing the camera in a fall. The other mounts that use double sided tape to mount to the helmet do stay on well, but in a fall you could loose the camera. The head/helmet mount thats a strap like a head lamp is cool, but have seen others fall in powder and loose the camera. The biggest down fall is battery life in the cold. Other than that the quality is the best out there right now. The wideness of the lens is great, but mounting on your helmet makes you look like a weirdo.
