We bought one of these cases and after assembling it and using it for DVDs, we bought two more units, one for CDs and one for paperback books.  They are well made, easy to assemble IF you follow the clearly written instructions.  We can't recommend them highly enough for everyday practical storage that works!  The piles of CDs and DVDs are now so neatly arranged with the adjustable shelving that we are inspired to watch more movies.
