Eva M. ★★★★★

The rubber ball has just the right amount of give to lock into my cradle without any wobble, and the 5/16" threaded stud fit my existing hardware perfectly. Install took under a minute, solid as a rock.

Matthew K. ★★★★★

The threaded stud was exactly the right size for my existing gear, and the rubber ball locks in place without any wobble.

Charlotte ★★★★★

The 1" rubber ball grips tight in the cradle without any wobble, and the threaded stud screwed on cleanly to my existing mount. Exactly the B size I needed, solid build that should hold up for years.
