This is by far the best bike mount I have ever found and it will be my go to from. I will be ordering some more in the future. Why do I say this well it is the most secure mount with a sensible 1/4" connection screw for the camera or whatever you want to mount combined with a clever tapered positioner for the adaptors. it enables me to mount anything securely but to easily position the devise by unlocking the screw and turning on the tapered positioned.
