I bought two 77" shelving units. They were very easy to put together. They are very sturdy and seem to be exactly what I wanted. Everything is great about these shelves. HOWEVER, the factory quality control is poor to say the least. Out of the two units, there was damage in both packages. This damage is from the factory because the packaging had no damage at all. One of the cross braces at the bottom of the end piece is bent and twisted. The wire rack had a broken weld. And one of the braces with the big rivets in it was bent and the rivet was smashed when installed at the factory. For the money I spent on these I'd expect a little higher quality of a product.  I checked the "NO" for recommend this product to a friend because I'd be embarrassed to recommend a product that may come out of the package damaged from the factory.
