This is a practical item to have around the house for carting heavy things around. It seems like it should be able to support a good amount of weight. My only complaint is that I had to use some force to connect the final two pieces together, and as a result there's a bit of an arc that causes one wheel to always be off the ground. I loosened all the nuts and tried to correct this to no avail. Also, hand-tightening using the included wrench was a real chore, as there are 16 nuts to tighten. I'd recommend using a socket wrench or a power drill with a socket adapter.
