Ellie R. ★★★★★ Oct 23, 2026

The two-hole pattern lined up perfectly with the pre-drilled holes on my console, making installation a breeze. The ball itself is solid and grips my RAM arm securely without any wobble. Exactly what I needed for a clean, stable mount.

Ella ★★★★★ Oct 21, 2026

The two-hole pattern gave me plenty of mounting options without needing extra adapters, and the ball base feels solidly machined. It clicked right into my existing setup, and I can already tell it’ll hold up to some serious vibration.

Sophia ★★★★★ Oct 18, 2026

Wasn't sure if the 2-hole pattern would line up with my existing setup, but it fit perfectly and the ball is rock solid once tightened. Exactly what I needed to extend the mount without any wobble.
