eero is a mesh WiFi system, and it comes with an eero (basically the router) along with two eero beacons, that you can place anywhere in your home. This is going to allow you to improve the WiFi connectivity throughout your home, and blanket your home in WiFi which is always a good thing to see here. If you have a home that has pretty thick walls, or is made of bricks, than a mesh WiFi system is going to be great for you, as it will be able to penetrate through those walls, so there are no more deadspots. Now it does work with Alexa, but the commands aren't as robust as with some other devices. But you can ask Alexa to pause eero, so that everyone comes down to eat dinner at night, or so you can get their attention.eero Home WiFi System & Echo Dot (3rd Gen) - Amazon - $349
