c_tailswrote a review of GoPro Chest Mount Harness on August 28, 2013
Familiarity: I've used it several times
The harness fits well and secures the camera well. However, it doesn't have quite enough range of motion to keep the camera facing forward when seated on a bike. The result is you get great video of the ground, but not enough of the horizon. Need to add an extra link between the camera and mount to improve the range of motion.
