Really solid, great mount! Some notes added
This mount is awesome! Build quality is excellent, super solid metal or composite material. It fits my LFE Advanced perfectly. One note for the performance, I added some foam underneath the mount to float it on my hardwood floor. It's mounted under my couch. Sitting directly on the floor under my couch is ok, but adding some foam underneath the mount so it's not directly on the floor greatly enhances the experience. I'm using the rubber feet provided in the kit and they work great.
