Not fit for purpose. Regularly loses the wireless network. Extremely frustrating process to reconnect, if you can connect at all. Then the next day it is lost again. Start over. The system is not really useable. The system I have bought has to be junked. Probably the worst product I have ever bought. Shame as when it works, it sounds great. But nowadays that is a rare occurance. As other reviewers have pointed out, one start is too high. DO NOT purchase SONOS. The company evidently has contempt for its customers.
