Of the many different bookcases that I have assembled over the years this is easily the best of the bunch.  Everything lined up and came together as it should, producing an attractive and solid bookcase.  Fittings and hardware worked really well.  Assembly instructions are good.  Putting the unit together was straightforward and could be completed in less than an hour and a half.  Unit is quite stable on carpet when it is upright because of its depth.  Unit comes with a marker to cover any scratches (there were, however, no marred surfaces).  People have commented that it is an attractive bookcase.  If I needed more shelving I would not hesitate to buy more of these units.  Great value.
