It's been in about a week. We got the one Pro 6 for 2000 SQFT. Prior, we tried a wifi extender but that didn't help. We had 2 locations in the house that were furthest away from the old modem/router combo we had, that were always buffering or just slow. I swapped out my modem for a standalone modem and installed the eero (super easy installation) and so far so good. We have not seen any buffering. I have my router just wired into the modem. Haven't tried moving it around at all but might to see how it does. The house is 1800sqft but that doesn't include the basement which I don't really know how much sqft that adds.. but one of our TV's are down there. We have many devices on at once. I love how I can assign devices to a person .. this makes it so I can shut down all my son's stuff at night. I also love the guest wifi - I have separate PW for guests. I haven't tried the Pro Plus yet but I'm thinking about it. It comes with a VPN which I probably should have anyway. It also seems to have a lot of features like backups and activity reporting and scheduling which will make it easier to control the kids wifi time.Overall I am happy .. Got a good deal during PRIME day.
