Should have bought them sooner
I was using Google home speakers and they just continually spluttered and popped as they tried to sync. That was a single room, let alone the house. I finally gave up. Then I tried Sonos. What. A. Difference. It just works. I don't spend ages looking at a waiting spinner when I decide what music to play. I don't listen to speakers stopping and starting. Just perfectly in-sync whole-house audio. And good quality speakers too. Very pleased.
