This is possibly one of the best mounting kits I've ever purchased. I like the fact that there are pieces so the mounting kit can cater to all models of TV. (Whether they have a rounded or flat back). Mine had a flat back so I didn't need the extra piece, but once that step was cleared it was only a matter of minutes before it went up on my wall.  The adjustable arm is nice, as it is setup in our bedroom. At night the TV is angled towards the bed and makes it super easy for both of us to see up on the wall, and during the day its turned in another direction towards my desk - also making the ability to view the TV while working.
