@moira I’m no expert, but have been happy running Eero for over a decade now. Pretty much has been set it and forget it.
Only downside I’ve run into is that the mesh system (and this may be typical for mesh systems, I dunno) doesn’t let you designate separate 5 and 2.4 (or whatever it is) networks. Which was never an issue until we got our new hybrid car that has CarPlay, but complains because it can’t scan for CarPlay if connected to a 5 GHz network, and tells you to put it on a 2.4 GHz network. My solution was to prioritize CarPlay and tell it to forget our home network. If you don’t have CarPlay, or don’t connect your car to your home network, this may not be an issue.
