Samuel O. ★★★★★

I was pleasantly surprised by how solid the 1" rubber ball feels when I lock it into the mount—no wobble at all. The threaded stud is exactly 8mm as described, which saved me from needing an adapter. This little piece just works perfectly for my setup.

Julian L. ★★★★★

The M8 threaded stud fit perfectly into my motorcycle's existing hole, and that 1-inch rubber ball grips the mount arm securely without any wobble. Setup was a breeze and it feels solid even on bumpy roads.

Hannah ★★★★★

The rubber ball on this mount has just the right amount of give to absorb vibration without feeling loose. I used it to secure a GPS on my ATV, and the M8 threaded stud fit perfectly into the existing bracket hole. Solid little piece of hardware.
