Penelope ★★★★★ Oct 23, 2026

The rubber ball and flat base combo is surprisingly sturdy for mounting my GoPro. The 3/8"-16 threaded hole lined up perfectly with my existing arm, and the 1.5" ball gives just enough flexibility for adjusting the angle.

Brian ★★★★★ Oct 22, 2026

The pre-drilled AMPS hole pattern made installation on my existing mount bracket a breeze. The rubber ball grips my device holder firmly, even on bumpy roads.

Michael ★★★★★ Oct 21, 2026

The 2.5" base fit perfectly into my existing mounting holes, and the 3/8"-16 threaded hole made attaching my device arm incredibly simple. It feels rock solid with no wobble, exactly what I needed for a secure setup.
