Lacks features of more expensive mounts - such as cable routing, tension adjustments and a detachable mounting plate. With other mounts I've purchased, you can install them by yourself by attaching a plate to the TV first, attaching the arm by itself to the wall, then lift up the TV and hook it onto the arm. For this one you need two people - one to hold it up in the air and the other to screw it to the plate). I have several of these mounts at the office and recommend them as a good value, as long as you have someone to help you put it up. Would add the 5th star if the mounting plate was detachable with an easy mount hook on it.
