Grace ★★★★★

I was a bit worried the rubber ball might feel cheap, but it's actually quite firm and grips well. The hole spacing on the diamond base matched my existing mount perfectly, making installation a breeze.

Michael ★★★★★

The diamond base lines up perfectly with the existing holes on my device, so installation took under five minutes. The 1-inch rubber ball feels solid and holds its position even on rough roads.

Abigail P. ★★★★★

Needed a solid mounting solution for my GPS unit, and the rubber ball on this diamond base grips perfectly in the cradle without any wobble. The two mounting holes lined up exactly with my existing drill pattern, so installation took under five minutes.
