Does the job we ordered it to do. I followed the instructions for 400x400 and have "bunny ears," as we've been calling them, sticking up past the top of the TV. The holes on the back of our television are not centered though, so I don't think it's the mount, or anything we did wrong. If the four holes were centered on the back it would be fine. We have an LG5600, 42inches. Full motion mount. TV tilts up and down, side to side, along with arm that moves side to side. Great for corner mounting. Easy installation using stud finder, drill, and level. Will be buying another for a different TV. Also have another mount by Videosecu bought 6yrs ago that's held up well. Haven't given it any thought since we put it up in our living room with a 47in Samsung.
