Well designed!  The shelves are just the right size for DVD player and DVR.  Hides wires adequately to keep it looking neat (but I recommend using a cord cover kit to continue hiding the wires down the wall below the mount).  All parts needed were included, somewhat easy install.  Smooth horizontal swivel and easy vertical adjustment (needs metric socket wrench not included).  TV and shelves adjustable location along track.  Need to properly square up the shelves when installing to shelf mount as it attaches to peel-off sticky surface so they look straight.  Must be mounted to wall stud.
