The directions were clear and everything worked. The only hiccup occurred when I decided to change the position of the mount's connection to the TV and it would not quite fit without substituting 4 smaller washers. Everything was fine for the 46" LED TV set I mounted on the wall.
only took a half hour to install on the wall and get the TV mounted. it comes with all the hardware and instructions. you just need a decent drill and a 1/2" ratchet and you're all set. mine even came with a level! i'm feeling good about this purchase.
