Love it
I like that it does what it says it will. No fuss. My kids and I use it as information but don’t need to interact with it. Weather, calendar, even upcoming subways. Knicks schedule. Dad jokes. It’s so low key and low maintenance. My ONLY complaint is there isn’t a way to use it as an accurate clock.

A nice to have - in my kitchen
Almost perfect. It could be easier to change/update its apps and sometimes ghosting between a photo and the weather app is an issue. But both are minor flaws. It's very nice to see it, every morning, in our kitchen. We use it for our family shared calendar, weather and some nice photos from our last trip. Battery is very good.

Great device, easy to configure.
It is a family planner now. Showing trash collection days, schedule, energy prices and weather. And it's been great. You hardly notice it, unless you want an update for the day. Especially during morning routine it's helped tremendously.
