Had the video doorbell 2 which was constantly giving false reports and never worked properly but I thought that perhaps the #3 would be improved. What a mistake! It never covers the programmed areas properly and mostly misses everyone coming to the door, it constantly gives false reports, was never able to connect it with Alexa ( like it says it will ), was never able to talk to whoever was at the door, battery life is terrible so I had to get two batteries, and now it is almost constantly off line as the batteries don’t stay fixed in place and have to be reinserted at least 2-3 times a day.
Guess it works by making us go the front door constantly to fix the batteries!
