Used to mount a 47" LG LCD.  I keep this thing extended fully from the wall almost all of the time with the tv at a perpendicular angle to the wall.  I was skeptical any stand would hold up for this kind of use long term.  Its pretty easy to install even if there weren't instructions (2 bolts).  It's held up perfectly so far, no wobble or anything.  Feels sturdy like it will last forever.  Good buy.
