It took a little while to become comfortable with the setup. Once we did it was very easy. It does take a little while to setup each pair. You can have 20 separate transmitters paired to 20 separate receivers and each combination can have it's own ring tone. That would leave my head spinning, but it's possible.The two receivers + three transmitters are perfect for a store front with a back door for deliveries. One sensor on each of the double front doors, set to the same ring tone on each receiver. The back door can have it's own ring tone on each receiver.
