Super simple (once you Google "how do you sync multiple Google Homes?")...I Google questions instead of finding them in the user guide. Amazon Echo wasn't a difficult setup to me but I can sure see how it could be to some, but it's amazing how much easier Google has made the setup process. It's truly a plug and play environment. Not just talking syncing because as we know, you can't sync the Echos/Dots. The sound quality is (imo) wonderful
