Can you elaborate on the benefits you see from this setup? I ran a Unifi setup for about a year before tearing it out and replacing it with an older Linksys 1900ACS. The Unifi took an enormous amount of trouble to setup to provide worse coverage than the Linksys for 3x the price. Not only that but it was a huge eyesore, with 3 different units with 3 wall warts all intertangled with cat6 cable. All of that on top of the recent scandals and I couldn't be happier throwing it into storage.
I've found Unifi to be a pain to set up just right. But once you've got things just right, it's generally pretty fast and reliable.
I heard that Ubiquiti went through an outsourcing / cost cutting phase recently and a lot of complaints about their software.
So I spent a little more and went with Aruba Instant On and it seems good so far. I really just wanted the ability to make however many VLANs I wanted.
