I bought eero since I was excited to fix my hard-to-cable apartment problems. They advertised on their front page "never reboot your router again!".
When I got them they failed to work well, and cabling the back-haul led to even worse performance. When you log into the support system, the first suggestion is "reboot your eero".
Great work, guys. So I returned it and got Plume and it kicks way more arse.
FWIW, eero doesn't say any more that you'll never reboot your router again, but it's still the first item in the trouble shooting guide. I'm not sure I've ever had to reboot any Plume nodes.
