The unifi ac pro's work awesome, consumer routers are kind of mickey mouse after these are deployed. Mounted them in a ceiling like a smoke alarm connected via ethernet, on the other end is an included poe injector unit or just use can use a switched hub with poe ports like ubiquiti edgerouter. The only thing I don't like is the management tool requiring java for the browser but it's pretty simple to figure out. Overall it's cheaper than these other mesh products.

If you need a router functionality, get there edgerouter but I'll tell you this, it's super powerful but not something easy to figure unless you have a deeper understanding of network protocols. Great stuff.
