This TV wall mount doesn't mess around with fancy features, like tilting, angling, or movability. It is just a straight-forward wall mount for a flat-screen TV. It easily handles our 55" screen.
A couple things that I like are the fact that you can easily slide the TV left or right to center it on the wall, even if the bracket is not installed in the exact center of the wall. That helps for mounting the bracket securely into wall studs. Also, when the TV is mounted, you can still tilt the bottom of the TV outward a few inches when you need more space to access cables. Not a lot of extra space, but was just enough for my needs. When you're done with cabling and let go of the bottom of the TV, it doesn't stay tilted, but will return to being flat against the wall.
The straps on the unit have nothing to do with mounting and supporting the TV. They are there for when you want to dismount the TV from the wall bracket. Typically, the TV is securely "locked" onto the bracket. Pulling downward on the straps will allow you to release the TV from the bracket and take it down.
One downside I encountered: various screws were provided to help mount my TV to the bracket hardware. The correct screw size was supplied in two different lengths -- one too short and one too long. I had to run to the hardware store to purchase a few screws to complete the job.
