Chloe E. ★★★★★

Clamped this onto a 1.5-inch square post on my boat, and the 1" ball locks in solidly with no wobble. Perfect fit for the RAM arm I already had.

Alexander ★★★★★

Tightened this onto my boat's radar arch and the 1.7-inch clamp holds perfectly even through rough chop, no slipping at all.

Sophia ★★★★★

That 1-inch ball on the clamp locks in tight and hasn't budged an inch on my slightly undersized post. The whole thing feels rock solid even with my tablet mount fully extended.
