Works great on my Vizio 42" LCD. The TV's weight is about 38 lbs., and the wall mount's capacity is 100 lbs. I thought that perhaps the mounting plate might not be large enough for the TV, but there is plenty of room, especially since the mount comes with additional side plates to expand the mounting area for an even larger TV.Easy to install, and in the 6 weeks I've had it up, it has required NO additional adjustments since the first day.The ONE thing to be aware of is that it doesn't extend that far from the wall, so the range of rotation that the TV can go is LESS than the wall mount's actual range. This, of course, may or may not be a problem - - it depends on just how "off center" your needs are. Although our TV/mount does not rotate more than about 30, we can very comfortably watch the TV when we're sitting 60 from the wall.Bottom line, I would buy another one once I get a second LCD...
