Your review: this cart gets abused all day long. It's usually overloaded to the point that it cannot accept another sheet of plywood and it rolls around just fine. Wheels were properly matched to the cart.
Pros: Makes it easy to move a large amount of material quickly and easily on smooth surfaces.
Cons: It takes a year or more, but in an oily shop the wheel material breaks down allowing the carbon in the wheels to leave black marks on the urethane and epoxy floors.
