Looks like an interesting product. I built my own setup to achieve this with a repurposed Dell running 10GB/2.5GB network card on Opnsense, Netgear switch with 4-port 10GB (2x SFP 2x LAN) 24-port 1GB, a couple of 8-port 2.5GB switches and a few Extreme Networks APs including one outside in the garden.
All second hand enterprise hardware that cost similar to my original Asus mesh system.
I love seeing full Yayzi speed on wired devices!
