Promaster 68572 Articulating Arm & Clamp

I was skeptical about how well the clamp would grip my round light stand, but the rubber pads hold it rock-solid without any slipping. The arm itself locks tight in position with just a turn of the knob, making adjustments effortless.

The clamp grips both my desk edge and a round pole without slipping, and the articulating knuckles hold their position firmly once tightened. Setup took under a minute, though it's a bit bulkier than I expected for a travel kit.

Took a bit of fiddling to get the grip just right on a round pole, but once it was seated, the clamp held firm all afternoon. The articulating joints let me position my light exactly where I needed it without any sag, which is what I was hoping for.
