My unit arrived witht the box totally beat up in shipping.  Amazingly the unit was in good shape, due to great inside packing.  It went together with just a few wrong aassembly steps from me.  As I was building it I got to thinking it will never hold the weight of over 500 CDs.  The wall mount system looked too lightweight to hold what it was advertised for.  Have you ever put 500+ CDs in a box and tried to lift it!  After mounting and filling up, it looks beautiful and one week later is still hanging around, no sagging or problems.  It looks very nice and I'm thinking of getting another, smaller one!    tw Austin, TX.
