Does it hold the TV on the wall? Yes. Is that about it? Yes.
I bought two of these mounts - one for my upstairs TV and one for my downstairs TV. I realize that I bought the most basic of wall mounts, but that is all I wanted - something super slim to hold the TV on the wall. However, I have two issues with this mount. First, the screws included with the mount are absolutely terrible. When installing the first mount, even after pre-drilling the holes, the two of the four screws stripped out on me while sticking out about a half an inch from the wall. This made it almost impossible to get them all the way into the wall. So when installing the second mount, not only did I pre-drill the holes, I even ran the screws in prior to actually securing the mount. Same thing. My advice here... ditch the screws that come with it and get some hex head lag screws in same size. At least you know you can get them back out of the wall if you need to.
Second, after getting the mounts secured and the TVs mounted, both of my TVs are slightly crooked. I used a laser level on both templates and the mounts to make sure they were straight, but they are still just a little off. However, on a 65" TV, a little off looks terrible. I tried adjusting the mounts on the back of the TV, but there isn't any room to move them.
Looking back, I should have just bought a full motion mount and lived with it sitting off the wall a bit further.
