This was a familiar item to me, since I already own the double wide size cabinet, and I needed some more storage space for DVDs.  I did notice that, unlike the double wide version, it has a tendency to tip forward when the doors are open.  This was easily solved by inserting a standard shim (pack of 50 less than $2 at Lowes) on each side of the bottom front of the cabinet, then pushing them in so they are hidden.  Just for good measure, I also attached a drywall screw to the top piece in the back as well as one in the wall, and connected them with some twine.  After inserting the shims, however, there is no movement.  Very nice piece.
