This is the first time I set up a wall mount for a TV, I wish I had done it earlier, it was a lot easier to install than I expected and gives a lot of freedom to use the TV. It also feels really sturdy and strong for a big 70" TV.
If anything, the only criticism I have (considering this is the only product of this category I have ever bought), changing the angle or position of the TV with the mount feels a bit too hard. Like maybe the screws are too tight to keep the TV in place. That could be a positive as I would image in time they get loose? Specially after usage, but currently, I feel uncomfortable having to press so much on the TV to get it to move. Changing the vertical angle is also pretty hard, if you need to change it often. If it is set it up once and then forget about it then it is pretty decent.
