I purchased a CD cabinet recently.  It was rather challenging to assemble.  I followed all of the instructions precisely, yet the finished product was rickety and not stable.  I tried putting the doors onto the cabinet.  One of the two doors was about an inch and a quarter too vertically.  If the "down wheels" rest in the groove on the base of the unit, the metal pin at the top of the door (which I installed correctly) does not go up high enough to fit into the groove at the top of the unit, so the door simply falls out.  This is frustrating.  I am going to have to buy some longer dowels, I suppose, paint them black, and insert them into the door to make it fit, but there will still be a large gap at the top of the door--unsightly.  I would not buy this product again.
