We had a problem with our Internet connection first but after it was solved this system works so well. We replaced our router as our Ring doorbell did not have a good image and especially sound quality but now with the eero 6 the sound on the doorbell side is perfect. With the Echoshow the sound on the doorbell side outside was terrible, but with this new network the sound is loud and clear. I will be able to finally use my doorbell to its full potential! The quality of streaming on the TV is also improved with almost no disconnection. We were getting disconnected very often before with our previous router. It was very easy to configure. We are now on the trial plan for the security + service and not sure I will keep that. it's king of expensive and I already have a firewall and antivirus, antiransomware etc.
The add blocker seem to work ok too. So far it is a very reliable system.
