Great Video Camera!
This is a great video camera. It is small, light and simple to use. I have used it mountain biking with the handlebar mount, whitewater rafting with the waterproof case and with my mountain bike helmet. I find it works best mounted on top of the head vs. side mounted. When sidemounted it tends to pull the light mountain bike helmet to the side. I have also used it with my mountaineering helmet during a climb on the Grand Teton where my partner fell and broke her leg. She made a sweet video.

I normally use the waterproof case to protect the camera from dirt, moisture and lens scratches. One caveat, the audio sucks with the case.
It is easy to know if you are recording with both lights and audio beeps. The small leash is weak and should not be trusted to prevent loss of the camera in case of a serious fall.
Overall, I recommend this camera and look forward to using it this winter while getting face shots!
