K&M 23720 3/8"

On paper this clamp is fantastic. Many points to connect gooseneck holders and built quite strong, I can't see it breaking any time soon.

However! The circular tightening knob doesn't give you any purchase at all, and you can't really secure it properly. So as such it tends to move around a lot when trying to adjust mic position, which gets very annoying. A regular wingnut style tightening handle would make this 10/10, but as it stands (pun intended) Its more of a 5/10
