Very pleased with the product.  Easy to put together, Looks good.  Be aware that the upper half of the back is cardboard.  This doesn't seem to affect the stability (the lower half of the back is the same material as the rest of the bookcase), but it does mean that the bookcase has to be placed so that the back is not visible.  As I recall, the site says the shelves hold 27 pounds, but the instruction book put the upper limit of the weight load at 50 pounds.

Pros: Ease of assembly; very good value for the price; very stable.
