If you had asked me what I think about this unit while I was getting in my car to head to the hardware store to get some real wall anchors I would have rated it a 2 or 3 star.  Throw away the cheap plastic anchors and go get the metal ones in my photos.  These are solid and this shelf isnt going anywhere.  As the other reviews state though, be very, very careful when measuring the screw locations or youll have a heck of a time getting this thing on the wall.  Once all of that is taken care if though...I couldnt be happier with the shelf and my son LOVES it.  He really needed a little extra space in his room.
