Decided it was time to move up to the 20th century and get a doorbell in my old house. It's an old 1940s frame house with 3 porches off the back (hey, it's WV).
Setup took about a minute. Just pair the buttons with receivers. You get 2 receivers and two push button units. You can set each a separate tone for each push button unit. Receivers plug into standard wall socket. Push button units are waterproof, come with 3M double sided tape to stick them next to the front door. The ring tones are all basically ding/dong.
Fast and easy.
