For the price, this is awsesome. Very easy to set up and get running. The remotes are sized so that I could use the same holes as my old doorbells and I like that I can easily slip off the remote from the base for battery replacement. Having the extra reciever allowed me to place one on each floor so i can always know if someone is at either door. I also liked the large selection of chimes and set mine up so that each door has its own chime.
