Overall we are very happy with the product. For the low price, it is easy to assemble, and is a pretty sturdy piece of furniture. The only thing that massively let it down however are the plastic shelf supports provided. After loading the shelves with all of our books, the supports eventually sheared off. The customer service we received however was excellent and we were able to remedy the problem ourselves by drilling out the plastic that had been left in the holes and installing some more sturdy metal ones. Had metal shelf supports been supplied (they only cost a few pence each), we would have given this a five star rating, seeing as they are an integral part of the bookcase. 

Overall, highly recommended, but if you do buy this, please invest in some metal shelf supports as the plastic ones will snap.
