This item is listed as a "commercial" grade rack, and it lives up to that claim.  The box was beat up when it arrived, and some of the little black packing spacers were broken, but that had no bearing on the actual shelving.  The shelves are heavy duty and the whole rack looks really professional.

Pros: Very sturdy shelving, thick rubber wheels, deep plastic bins, very easy to put together - no tools required.
Cons: None
