I installed an 80 lb., 50" plasma in my house with this mount. The room is long and narrow, so I needed a very flexible mount that would swivel to face wherever one is watching from. This mount has a very large range of motion, is very easy to move, and feels like it could support twice the weight it's holding. Installation took no more than 30 minutes. As others have noted, make sure you secrurely fasten it into more than one wall stud, and follow the TV manufacturer's recommendation on the length of the mounting bolts. Price was fantastic- I've seen others listed for 3-4 times the price and can't imagine them working any better than this one.
