Good stability and adjustment by a clamping knob that is effective. My servant does not receive heavy objects but the rotation of the roll is good, without much friction. The transition roller / ball is very easy but beware, the height from the ground will not be the same (the ball is a little higher than a few centimeters).
Only regret: no side stops to prevent the supported lengths fall if it exceeds the roll area. On the other model (wolfcraft) are equipped. So, we sometimes regret the narrow roll, Good price / quality ratio and easy to install with standard tools.
