Finally, an arm that actually stays locked in place with heavier reflectors—the brass mounting hardware gives me way more confidence than the all-metal ones I've used before. Sets up and adjusts in seconds without fighting it.

The sliding center collar makes mounting this to a light stand incredibly quick, and the brass locks hold tight even when I angle the reflector awkwardly. It’s sturdy without being a hassle to adjust mid-shoot, which is exactly what I needed for bouncing light on location.

The brass locking mechanism feels really solid, no wobble at all once tightened. Used it to hold a large scrim on a stand last shoot and it handled the weight perfectly.
