I was ready to return my original Sonos system. I had all sorts of problems with audio dropping out of the rear speakers and subwoofer. I ended up buying BOOST and it made a huge difference. Everything works as expected and the quality of the whole system is incredible. If you have many barriers in your home that can affect the quality of your wireless signal, buy this product. I've found that the "extenders" used in many wireless products just don't work well with Sonos. Just get this product and call it good.
