As good as the reviews say it is and as easy to mount.  I was able to do it alone by mounting the X frame to the TV after removing it by separating the long center bolt between the dual and single extension arms.  Just be aware, replacing that bolt is MUCH easier with a second person but everything else is a breeze.  Oh and all the extras screws for swapping out different sets is a plus.  I mounted a 32" ultra thin (15 lbs) Samsung LED.
