I bought the unit 2 months age. One day ring notified me of someone at My door. It was an appt I made that I have forgotten. So I picked up to Talk to the person and came back home to meet with them.
Very happy with this item and chime pro! It was easy to install and worked like a charm. We were having packaged stolen. Now we can see who is around our house. Looking into getting another one for back door.
