I certainly had my doubts about mounting a 150+ pound tv, but The Beast handles it no problem! It was great in the basement where changing the angle is a must in case people watching also want to be doing other activities without missing a moment of the action. We don’t leave the arms fully extended for significant amounts of time, but no issues at all in terms of pulling from the wall or sagging in the mount; no issues of any kind for that matter. Tv looks great in every seat, and all the cables are nice and managed behind the scenes.
I upgraded my theater room to a 98" LG. I had geek squad come out and mount the 86" that was removed to the family room. I have a tv nich over my fireplace. So I got the beast because of much it can extend. From back to front of the nich is 23". This may say 38". But it 39". I wanted to be able to get behind the tv without having to take it down. This works like a charm. Geek squad guys liked it so much, that their now going to recommend it to they're customers.
