Surprisingly well made, and designed. It is a bit hard to turn when you have a load on it, but that can be fixed by strapping two of the wheels so that only one on each side is in contact with the rolling surface. I cut a wood block to fit between the uprights and the upper wheels then strapped the wheels up against the wood. It works perfectly now as a two wheeler.
