I installed this TV wall mount in the basement for my wife to watch TV or workout programs while exercising.
The bracket came with everything needed for a complete installation other than tools, which I already own. The only assembly required was to mount the TV bars to the back of the TV using the included screws and spacers (be careful to use the correct length screw, or add spacers so the screw doesn't bottom out in the hole and damage the screen).
The kit includes a spirit level to ensure a level installation, and then once the wall plate is bolted to your studs and the TV bars are affixed to the TV and set at the desired angle, you just hang the TV on the wall plate and pull the two lanyards to release the clips so the TV can latch in. You can then slide the TV left and right a bit to center it on the wall.
I like that the mount keeps the TV close to the wall, but still provides enough space behind the TV to connect cables or tuck a cable/streaming box behind the TV for a clean installation.
