Got this to replace a Peerless Paramount wall mount when I got my new TV.  Let me start off by saying it works as advertised.  But that won't get you 5 stars.  The problem is installation.  Maybe it's my own fault for thinking all TV wall mounts worked like the Peerless I had.  See, that one has a separate TV plate that you screw to the TV first.  Then you have the second piece (the actual wall mount) that you screw to the wall.  Once that's done, using the bracket mounted on the TV, you hang the TV on the wall mount and secure it with a single bolt.  One person can easily put a TV on the wall.
