I used this mount for putting a 42" LCD screen on a wall.  It is a solid and sturdy mount.  I was extremely pleased by the quality.  Hex head lag screws that are included which are a breeze to drive into the stud.  I purchased a mount previously that had a phillips head on the lag screws and that really made them a job to drive into the stud.  Since the TV was rather large (400x400 vesa mounting pattern) I had to use the extension arms off of the main plate as shown in the picture.  They were surprisingly very easy to attach.  A nice plastic cover is included which slides back over the wall mounting plate to conceal the mounting screws - I thought that was a nice touch.
