Review on Graham Field 3085DZ: Efficient Clamp Compressor Tubing for Medical Use by Michael Gutierrez

The overall build quality of these clamps is pretty poor. The movable legs periodically tip and get stuck - usually multiple times as the clamp is tightened over light-weight surgical tubing. This makes them quite difficult to clamp completely. Worse, because the yoke is binding and not moving, it often looks like it's compressing the pipe completely to create a seal, but it's really just the yoke itself that's binding. This caused several leaks when I was using them. I won't buy them again.
