I installed this monitor arm through a hole in my desk top. Installation was easy and straight forward. I don't like that 2 of the connections (1 on each arm) are loose. I tightened them as much as I could with the provided Allen key but the joint would not tighten up, they are still loose. Also, the VESA adapter sits very loosely on the arm. There is a lot of play. I just wish the joints and the adjustments were a little tighter and better quality.
