Easy to install, easy to program 2 separate rings. One tune for front door and a different one on side door, so you know which door someone is at. Also, bluish circle on doorbell let's you easily see the bell. Our old bell was white on white on a white door jam. it all blended in and some people did not even see the old doorbell. Also, great range of volume control on the receivers.4 ranges, from very soft to pretty loud.
