As I lay here tonight hoping for some sleep time tunes, my wife asks as always ‘is sonos working?’. I check and as usual the answer is No. many years of ownership. Multiple speakers. Thousands invested. Dozens of hours troubleshooting. And sonos rarely works and never when i really want it to. Final judgement - nice concept. Maddeningly unstable. for a million reasons. especially for the price. not worth it. junk pile.
