This mount does the job of a Sonos mount for 1/3 the cost. Easy to assemble, easy to install. That being said, their hardware is a bit small so you can use some sturdier screws and make sure you hit at least two studs. As another user said, there's a hidden magnet on the right side about an inch from edge to bottom behind the foam that lets the soundbar know it's installed. They should remove this - for some reason Sonos has a soundbar that kills the bass when it detects it's installed.
