May take some trial and error
My first attempt with this mount was a complete failure. I mounted it on my bars with all the pivot arms to capture my favorite light DH trail. Tightened it up as much as I could and by the time I got to the end of the trail the camera was pointing down at my tire. The playback was also very shaky.
I'm sure this would be fine for lighter trail rides and on the road where there is much less impact.
Despite my initial failure with the mount, I'm rating it 3 stars due to the fact that it's not just a handlebar mount. I have yet to try any other mounting locations, but the potential is there.
Removed as many of the pivot arms as I could and tried mounting on my handlebars again. Worked MUCH better. Rode the same trails as my initial attempt and the camera stayed in place for the 2-3 hours I was out.
Upped my rating to 4 stars due to the fact that I was able to make it work.
