Review on Neewer 7-inch Adjustable Friction Articulating Magic Arm for DSLR Camera Rig, LED Light, Field Monitor, Flash, etc. by Jim Moody

I use it with flashes that weigh just under 300g / 10oz and it works great. The adjustment is as smooth as I need it to be, the flash clicks into place perfectly and the whole assembly is very solid (combination of only being 7 inches long and having all mechanical components properly sized).
