The box is a nice box, however, the wood splits in one screw only. I purchased 2 of these boxes and the same screw split the wood. It did not keep me from being able to use the box so I didn't send them back. The only explanation is that the particular hole was drilled too close to the edge of the wood. 
The wheels are of nice quality, the finish is very nice. The structure and supports provided for the box are adequate for the length.
