As a simple to deploy and effective mesh network it worked great in the limited testing I did.

As a wireless bridge to an existing wireless network it worked not at all. It requires a wired eero to use as a gateway so to use it as a bridge on an existing network you need two of them setup in bridge mode. Of course you would end up with a second wireless network in this case.

So I am going to have to keep searching for a reliable wireless bridge.
