This is a very well-planned kit: everything fit together well, and the weight-bearing parts seem to be sturdily constructed. Directions were clear. All parts were in the package. One of the half-circle columns had been damaged in transit, despite the careful packing; one email to the manufacturer resulted in their sending a replacement in about two days. Like most kits, the cardboard back is the "low point" of its quality. The bookcase is very attractive. We're very happy with it.
