This is a great wall mount.  I have installed three others and I like this the best.  It extends enough with the second arm so that you can mount a large TV so that it fits in the corner of a room.  The TV will hide the actual wall mount and arms mounting to the back of the TV.  This one was installed thru a plaster drywall into cinder block wall.  I used  the 2 wall anchors and bolts provided in the mounting accessory pack.  The 42" TV bolt pattern fit the mounting plate so I did not have to use the adjustable arms provided in the package.  Total installation time was less than 20 minutes.  I like the fact that you can tilt it, rotate it (makes it easy to get the TV level)  and move it in and out a great distance and it will go back pretty flush to the wall.  The instructions are easy to follow.  Overall, I think this is a sturdy mount that will confidently hold a large screen TV and it does not look like a massive mount like some do.
