This is a good product. Notice that the mount is supported by two flexible arms. This prevents the TV from rotating even when extended. This is going into the living room. I installed a smaller mount in a bed room with a single arm, which makes it very difficult to keep level. Since this is designed to mount up to a 60" it's very solid for our 40" and we can up grade to a 52" later. Included is hardware for mounting on wood framed walls or concrete block. Only weakness in the whole deal is that the single page of instructions don't explain anything. There are pictures only. But I think even a caveman could mount this.
