For the price this is a pretty decent shelf unit. It's not the most sturdy you can find, the shelves are non-adjustable for height, and the shelf support clamps are a bit cheap and 'ping' off easily, you just have to do one leg at a time. However, it supports a good amount of weight and three units fit my closet perfectly, so they were just what I needed. And the price is great. I just might buy more of these.

Pros: Cheap, solid enough
Cons: Non-adjustable shelves; a little bit fiddly to put together
