Not only are these great as you’re building out your smart setup, but they also work in groups by detecting which device you’re closest too. This means you really can’t have too many in your house. Despite the fact that the Dot isn’t really a great music player (get a bigger one with a better speaker for that), I use one in the bathroom for morning news and weather.
Often bundled in multiples, they work great to add voice coverage to your house including multiple room music, and voice communication between rooms.
This is the newest, 3rd Generation Echo Dot. It’s more expensive than the 2nd Gen but offers the same functionality.
