Used the mount for a projector. This design is so well thought out unlike other ones. It is quite rugged, sturdy and holds in place once set. The ball screw holds perfectly the load and you can safely tighten it without feeling it will break. I tested the projector at different angles and had the mount extended enough and retracted and the whole assembly was stable and did not shift in any direction. My projector is not a heavy one so I didn't test the mount to the rated load but the build is certainly there and I don't expect it will fail what's it rated for as long as you attach it to a wall stud using the provided screws which may be fairly big depending on what you use the mount for. I used smaller wood screws/attached to a wall stud to reduce the wall hole. Worked like a charm.
