The cabinet was not made very well at all.  All of the fasteners on the unit were drilled out too far leaving it with very weak connections at each joining corner.  Once the unit was up on the wall, the weight of it hanging allowed the pieces to shift in the poorly secured joints and now the door does not secure properly.  I plan to take it completely apart and try to glue each joint in an attempt to salvage the unit, but I am not very hopeful that it will go back together again.
