Sounds pretty decent actually.Yep, USB port doesn’t do anything. But they never claimed it did, so...
I like amplifi. I have five cubes and a teleport. Rock stable. Current up time nearly two months, and I’ve only had to reboot because of firmware updates. iOS app is great. It’s a little confusing that a few settings require going to a web page and the rest are in the app. The teleport is a very neat thing and I use it a lot. I get good Wi-Fi and wired performance. My outside connection is about 280mbps, and I understand some people with gigabit connections claim they don’t get full speed, but I have no experience with that so I can’t opine.
Something I was wondering, within the app does it show the current link speed with each device? I've always loved this feature with the AirPorts and not many other routers have this.
