The wheel collapsed under only 140 pounds, even though the maximum load is supposed to be 450 pounds. I think this happened when i was pulling it over the small curb of a driveway. The jolt must have made it collapse and the ball bearings all fell out. I didn't even notice it until the next time I used it.

Screws come loose
The first time I used this, all the bumping around from the road actually knocked several screws off and the wheel bent under the weight. It was reasonably easy to fix, on the upside. The screws have to be well tightened REGULARLY. I would recommend, but with reservations.
