Dash Mount Camera Holder Compatible with GoPro - Attaches to 20mm Mounting Ball

Fits the Tackform 20mm clamp and keeps it secured. Doesn't move at all, but you will need to toss the thumb screw on the clamp in favor of a M6-1.00 x 30mm cap screw with nylock nut. There is no way to get it tight enough without damaging the thumb screw. My order came with 2 of these mounts, which I thought was odd until I tightened the first one with the thumb screw and it broke the camera mount. Sheared it off completely. That's when I realized why it came with 2 mounts! Switched out the thumb screw for a cap screw and lock nut, tightened it down securely and no issues. I would give it 5 stars if it were not for the broken camera mount and thumb screw issues.
