Nice piece.  Assembles easily enough but the directions could be more clear, especially the diagrams.  The item is made of particle board but it feels study once it's all together and the finish looks good.    

This can be about an hour project.  The hanging mechanism is good but it does take a pretty decent drill to sink the 3 1/2 screws.  

As far as criticisms.  The picture depicts 6 shelves being used.  If you go for all eight shelves and blend CDs and DVDs, some shelves will end up off heights.  It works, but access to some shelves is a litle awkward.  
The side and center moldings look nice, but will obscure whatever item is closest to it,  An entire CD or movie will disappear behind it.
