Julien Persin 4 I found this backpack clip really sturdy and stable. The only problem I had is in cold winter my gopro would die quickly, and with the fixed mount it was not easy to quickly mount and unmount the camera. So I modified the clip with an aluminum quick mount and a 1/4" screw found on Amazon. Works great and looks pro!Note that there are additional 1/4" threaded holes for alternate mods.
