On balance, yes, worth it, and we picked ours up really cheaply at Costco, but there are a few really annoying things about our Ring doorbell.
You have to pay a subscription if you want to be able to look at historic videos (I know there are other brands you don't have to).
It regularly drops offline, and you get no warning or alert at all, so the first you know about it is when the Tesco driver is phoning to ask why you aren't answering the door. So irritating.
You need two batteries (or be prepared to have no doorbell for a few hours while it charges).
There isn't enough time to respond to the phone notification when you aren't home. By the time I've worked out how to speak to the person they are half way back down the drive.
It records some events, but then randomly ignores others. I can walk down the drive, get in my car and drive away.....nothing. But then a random bus goes past in the distance, and I get a nice recording.
So....could do better, Ring.
