Installed a week ago to hold a 75" Samsung 88# tv, the arm is fully extended as we needed it to be. There was a slight "bounce" when we placed the TV on the arm but that was it, held steady from there. Once the Christmas tree is down we'll be able to position it to completely hide where it attaches to the wall.
I had avoided mounting my tv over my fireplace for some time because it's deep and my tv is large. This mount works exceptionally well and installation was simple. It's fairly heavy and will take 2 persons but the long arm and flexibility are great. Holds weight perfectly.
This product was a great addition to our outdoor TVviewing area. It was easy to install, works great, and now offers a much broader range of seating locations for our outdoor TV viewing. We can even sit by our firepit and still have a clear view of the TV! We love it!
Totally happy with our purchase. We need to clear the fireplace and this goes well beyond it. Our TV is an LG 43 weighing only 16lbs. When the mount is fully extended you wouldn't know there's a TV on it. It glides smoothly and no rotation movement in the TV. Easy enough to install for us. Used the template, found studs 16 apart and drilled according to instructions. The wire holder is a nice feature too. Finally, we changed the arm configuration from left to right at the wall piece. Because when you fold it all in, the last arm (nearest the wall) will take more room then the wall plate. That's also why it can reach so far out when extended. We've very happy with it.
