I purchased a "bakers rack" version of this by another brand, and this one, at the same time. My intent was to make an "L, and make an inexpensive mudroom entry at the garage door. The other one arrived first, and was really disappointing. The shelves flexed, the bamboo shelf was thin and cheap feeling. This shelving unit arrived a couple of days later. WHAT a massive difference in quality! The shelves are firm, with no flex whatsoever, even the chrome looked better quality, it went together easier. Just a huge step up in quality over the first one by the other manufacturer. Side by side you can really see the difference.  I would highly recommend this brand. Wish I could return the other brand's rack. 

Pros: Quality metal, no flex, good chrome, wheels roll easily,  easy assemble. 
Cons: none at all!
