Thomas ★★★★★ Oct 23, 2026

I needed a sturdy ball mount for my truck’s dash, and the 1" rubber ball fits perfectly in the cradle without any wobble. That threaded stud was a breeze to install and feels solid.

Matthew ★★★★★ Oct 22, 2026

The threaded stud screwed right into my existing mounting plate without any issues, and the 1" rubber ball holds my tablet steady even on bumpy roads. Exactly the solid connection I needed.

Riley C. ★★★★★ Oct 20, 2026

The threaded stud is exactly 3/8"-16, which made swapping it onto my existing setup painless, and the rubber ball has just the right amount of give to hold my tablet steady on bumpy roads. I've only had it for a week, but it already feels rock solid.
