7|11|20 Inch Metal Articulating Magic Arm Super Clamp Holder Stand for DSLR Camera Photo Studio Photography Accessories Prop Kit

The stand is excellent. I already had a phone mount - I just screwed it onto the stand. 3 joints are tightened with one screw and this is very convenient. Holds reliably, although the lower paw could be of a different shape. It's more for a pipe than for a countertop. You have to press harder to prevent it from sliding, and this causes wear.
