We are very happy w/ the mount; it was easy to install.  I like the fact that all the hardware/screws come w/ the mount for any type of wall.  This made it even easier.  We've used (2) Peerless mounts (1) for a 26" Sharp and another model for a 42" Sharp. You can't beat the price, and the TVs are secure.  The only difficult thing was tightening the screw that keeps the tv from sliding once it's up.  The Allen wrench is plenty long enough, but the bottom ell kept hitting the wall, so we couldn't make a complete turn, and had to keep re-inserting and doing 3/4 turns.  If it was straight, I could have spun it around.  I guess it works well if the Tv is n\mounted w/ a larger gap from the wall.  Overall - very happy.
