Excellent attention to detail. Perfect fit of all components. Everything assembled smoothly, thanks to excellent detailed instructions and links to instructional videos (which we didn't need.) Assembly took about and hour-and-a-half, and would have been less had we read the instructions thoroughly first.

I would have liked the option of front-to-rear Pendaflex hangers, in addition to side-to-side. The hardware could have been separately bagged, by item, rather than in one large bag, which had to sorted out once opened. On the other hand, the only thing missing was the screw for the safety strap (there was a washer, though.)
It works best on a solid floor, because of the roller supporting the bottom drawer.
