This TV mount is easy to install.  Just follow the directions included.  I installed this near the ceiling and I'm using every bit of the 15 degree downward tilt.  Properly installed, the product is rock solid.  I installed a 32" tv on it.  I know it can hold much more.  The articulating arms are easily adjustable and if you want to tighten it down and lock it in position you can do that, too.
