Promaster Flex Arm HD (heavy duty)

I was nervous clamping my heavy external flash to this arm, but the locking mechanism holds rock-solid with zero drift. The increased load capacity over the standard model made all the difference for my off-camera lighting kit.

Finally, a flex arm that doesn't sag under a heavy flash and softbox combo. The sturdier build made framing my shots so much easier.

This thing held my 70-200mm lens and flash combo rock steady for a two-hour shoot, which my old arm definitely couldn't have managed. The heavier-duty build really makes the difference when you're positioning gear overhead and need it to stay put.
