Very nice that the knob doesn't come off. Quick to tighten and release. When tight, it does not loosen inadvertently.
This is a very good quick release clamp. It is interchangeable with other, more expensive systems. I have no complaints at all.
I have two of these screw type clamps, and I much prefer them over a lever type that I also have. Very well made - light, and screw is quick.
I use this clamp on my monopod and find that it works very well in attachimg my 80-200 f2.8 lens for nighttime sports photography (Highschool football)
