Thomas X. ★★★★★

Finally a magic arm that actually locks tight without slipping, the dual ball heads give me precise control for positioning my small monitor exactly where I need it. The 3-inch length is perfect for keeping things compact on my rig.

Penelope ★★★★★

I was skeptical about how sturdy a 3-inch arm could be, but the dual ball heads lock tight and hold my LED panel steady even at awkward angles. The 1/4"-20 threads fit perfectly on my light stand and camera cage, making setup a breeze.

Sebastian ★★★★★

This little 3-inch arm is surprisingly sturdy—it holds my field monitor steady even at awkward angles. The tension adjustment on the dual ball heads locks down tight without any slipping.
