These have been indispensable for adjusting my arms. The only thing I'd change is maybe to make it a hair thicker to give better thumb and finger purchase when tightening the clamps down.

Great Tool!
The tool is a great idea!! I have bad arthritis in my hands and maybe a little bigger tool for a little more leverage would be nice. I am sure there are others like me out there.
