I will strongly disagree on the support side. My experiences with them proved to be reason I ripped them out of my homes. Add to that the fractured product offerings with divergent features for no obvious reason. They enable HomeKit secure routing on one but not others in the exact same family of products. Their roadmap simply doesn't make sense.Eero is as well built as the next router, has VERY good support, constantly gets updates. And has some clever ideas like you can set it up to switch to use your phone cellular connection automatically if the Internet goes down, and the Eeero will use its WiFi network to send the signal round your home.
If you want to attack Eero you need to try harder, like the subscription model they use and how some even simple features are locked behind it.
You are right that their "subscription" model is completely bogus. High-cost/low-value.
The phone cellular connection is a nice feature, but not unique or innovative. I've been using a hotspot as a backup internet connection on my home network for more than 3 years.
Bottom line is that if you trust Amazon with access to your network, then go ahead and use Eero. Be sure to keep in mind Amazon's history when it comes to collecting and protecting private information. Amazon Data Breaches: Full Timeline Through 2023 (firewalltimes.com)
