This is an excellent product from GoPro. It's easy to get adjusted for a good fit, and it's very secure. I used wile out at sea on a PWC, and it didn't move! It's pretty easy to get the camera facing where you want it to. The actual mount point is the same as the adhesive mounts available for the GoPro cameras. It comes supplied with the J-shaped buckle, but you can also use the standard flat buckles if required.
Not sure whether it is just because this is a new mount, but the nut and bolt seemed to be fairly well secured in their various holders, making it a simple task to attache the camera to the equipped buckle.
