Although the materials seemed to be sufficient to support the TV, the bolts and screws used to hold it together, mount it to the TV and to the wall were less than adiquate. The instructions were hard to understand in some cases and completely wrong in other cases. As far as it fitting most TVs that it was rated for? We have one of the most popular and latest models on the market. I had manufacture an adapter, and buy larger bolts and screws for it. I wouldn't buy this model again.
We found this easy to install, however, the television is only level when it is in the extended position. When we push the tV so that it's flat against the wall, it isn't straight--it is very crooked. The weight of the TV in that position causes it to tilt cock-eyed. There is nothing you can do to fix it--trust us, we tried., I wouldn't buy this again!
