An avid triathlete I wanted to have a camera that is all madness and also participates in many ways. I then for the "Outdoor Edition" decided previously and thus had very good experiences. Skiing is very possible with the helmet mount, a mounting on the ski I have not directly tested. The first deep snow descent under blue sky then at home really surprised me: Excellent image quality and great, clear shots. Through the wide-angle and all acts usually somewhat faster than it actually is. The service I find very well done, perhaps not intuitive but practical: The lower button controls the shooting modes (camera, camera, timer photo, interval picture settings) as well as on / off. With the top button it then controls the recording, most camera on / off or take picture. When pressed for too long to the "On" switch then it can happen that you end up and then must continue pressing five times what a little bother in the Photo setting. The shooting underwater while swimming are good, here makes the headband good services. When cycling in the South had I know that we were staying in a place by the sea the problem and why we had rooms with high humidity. This meant that the then Helmet at speeds höhreren moisture in the housing condenses on the lens inside, which is a shame when you it noted later and the images are then washed out. Whether and how the open case provides a remedy, I have not tested, I had only one case here. The helmet mount is good, but it shows the weight of the camera in a lightweight cycling helmet at yet longer journeys and it is difficult to "just" to assemble or to film. I then usually filmed by hand and runs the helmet holder used. With a 16Gigabyte memory card, you must buy the way to you get a good two hours Video it in 960p at 48 frames. The battery is in the camera, the limiting factor and also keeps a good two hours, much shorter in cold weather, so that then arrange the most beautiful downhill the seven-time beep indicating the end of the movie pass. So if you, especially in long Want to film day trips much, can not avoid spare battery or battery pack. I'm going down there probably. Overall, a super compact and robust multi-sport camera with great attachment options, excellent photographs and extensive Accessories. Highly recommended!
