Love the simplicity. Hate the constant sell and subscription.
I love the simplicity of the new eero6 and while the range/power isn't best in class, it has been stable so far and sufficient for my use. For reference, I upgraded from an Apple Airport, and have previously owned Linksys, Netgear, TPLink, and Cisco products.
However, I hate the fact that basic management features like detailed activity monitoring are not available unless you pay a monthly subscription. I understand why features like ad blocking and content filtering are pay-for features, since they require a service to back them that has a cost to run and update. But management and visibility into my devices is something that doesn't require constant maintenance or a service to support it. It's not something I expect to pay additional for after paying for the devices themselves, especially considering the premium pricing eero charges: either you sell the devices as a loss leader for the subscription revenue model or you collect revenue on the hardware. You can't have it both ways.
Between this and the lack of access without Internet connectivity--probably related to the monthly subscription/cost for the eero's service based model--and these devices unfortunately becomes a non-starter for me. I'll be returning my 1x Pro 6 router and 2x 6 routers (I wanted the wired backhaul) and moving back to a more traditional networking hardware vendors products.
