This product actually surpassed my expectations.  It arrived timely and securely packed, and it was not difficult to put together.  The way it hung on the wall (a tongue and grove type connection) made it a breeze to install.  Merely put the two pieces on the wall and then hang the unit into it.  No holding up a heavy unit trying to keep it straight while holes were drilled into the wall.  Very secure connection.  We bought the smaller unit and still have plenty of room for additional CDs.  Great product
