Our Ring 3 went up after purchase in Black Friday, so we're about 9 months in and we're very happy with it.
The first month or so was spent getting used to it and defining the zones for the camera to cover, but since tuning that, it only alerts if someone walks onto the garden and cars can pass out in the road without detection.
The battery needs a charge about once every 7 weeks, but it emails me the alert at 30% charge which is at least another week's worth of use and it's a 2 minute job to remove the battery, though an overnight charge does mean a night without coverage.
I do hope it doesn't go kaput because it's been rock solid since installation.
One thing that puzzles me is that our usual Royal mail delivery and evri delivery drivers, who are friendly enough, firstly bang on the door, then 5 seconds later rattle the letterbox, then 5 seconds later press the Ring doorbell that is right in front of them?
