I love the Ring doorbell. I have installed several for clients, my own mother and I have one at my front door. They reason I like Ring Products so well is they work! I have installed several different brands of video doorbells over the years but they were often clunky to use and problematic.
I found the Ring products to be well designed and their app works better than I expect, their tech support actually answers the phone (my longest hold was 3 minutes) and best of all, my mother can use it.
