I would give 3.5 of what I could. It feels sturdy and I love that you can slide the TV out and that it comes with two mounting brackets. The downside is that it's not rectangular in shape. So in order to reach the height of the TV, you have to screw it to the wall in a slightly non-rectangular manner. It's hard to know exactly what angle you want without holding it there with the TV. There's also a small screw holding the TV in place that needs to be unscrewed to remove it if you want to move it to a second mount. This is a bit cumbersome as you need an Allen key to do it.
