The Sonos One is a nice addition to the home with the ability now to be able to voice control your music, rather than having to pick up your phone. The sound quality is great for its size and it is very simple to use.
It's very handy to play music/podcasts through this, as well as voice control items throughout the home. "Alexa, turn on bathroom heater" is very handy on those cold morning.
I have had instances where the Alexa integration has seemingly stopped working "Alexa, play Pink Floyd in Bedroom", "I'm sorry, that device isn't available" even though it's replying through the device. That is frustration; however easily fixed within 2 minutes by disabling the Sonos skill and speaker and re-enabling.
