I was expecting something better to be honest, as I ordered a similar one from the same company and the quality and complexity of this one are far worst than the other. 
This bookcase took much longer to assemble and had much more parts, although it appears in the picture as a simple one. 
In this price range, I'm happy with the purchase, it will do the job. 

Pros: Cheap
Cons: Low quality, many parts to assemble
