I have been wanting to get one. I like watching videos that are chest mounted the best. The helmet mount is to much head bobbing around and the bar mounts don't move enough to get feel of the ride.
I do like the rear facing ones when people are with other riders.
Have you watched any of the MotVlogs? There are some good ones.
