I have been using this camera this entire ski season. While I was switching from a Contour to this, it took me a little bit to get used to, but now, it's like second nature and super easy to use. The image quality on the GoPro compared to any other helmet camera I have personally seen is incredible. The app makes things easy to line up and make sure that you have the shot dialed before dropping in. I suggest getting a few extra batteries that are charged up and ready to replace the old when you run out in the mountains. Personally, I use the slim black case that is a lot smaller than the plastic case, but isn't water proof. For skiing, it seems to work just fine and the sound is better when you use the slim black case too. Photos with the Gopro are awesome, but I've been really digging the screen shots. Just pause the video and take a screen shot. Boom! Action packed.
