I love this model, it handles a wide range of sizes up to 70 inch, and can be adjusted almost any direction you could want. It almost doesn't matter how accurately you drill the initial holes because it will adjust to whatever you want. (Still take your time and mount it straight and responsibly.) The long arm lets it slide left and right along the wall to compensate where you want it in the room. and It will also extend pretty far away from the wall. It tilts up and down and It will even rotate tilt to adjust the left side of the tv up or the right side of the tv up. It is sturdy and even has room to install a low voltage outlet right in the middle of the mount. Don't waste the rest of your life with a flat against the wall mount that you can't see behind to plug in your HDMI cables. Build quality is very solid for something hidden behind your TV. It is plenty strong and comes with a lot of different screws and bolts for different TV sets and mounting options.
