I have both the 4 drawer bottom part, as well as the top hutch. The bottom drawers were verrrrrrry difficult to get them on the tracks correctly. The tracks are very poor quality. I thought I might have to return it, but decided to keep it. I just cant open the drawers too quickly or they will fall off the tracks. I might need to replace with different tracks in the future. The ball bearings fell out and were all over the floor, the metal warped, and the drawers just would NOT fit in properly. It was as if they were too small. 

The top hutch part is very nice, but again the doors were difficult to install and are still off centre no matter how we adjust the backs of them. Took over and hour and it's still not perfect. Frustrating, but I can live with it. I like the knobs and the piece is very heavy and feels solid.
