All I want is to hear a chiro when one of my doors is open. With this, you're stuck with either your choice of doorbell sounds, or early nokia ringtone sounds. They do work, they do sync pretty easily and are pretty easy to "program". I'll probably trash these soon though as I can't stand the sound choices. It's personal preference though
