I use this item for my classroom and it has been wonderful. When the students leave my room and come back they ring the doorbell to enter the room . I have a hallway from the door to the class room and it was hard to hear the students when they would knock to get back in. This works really well for when they return. I can also use the second ringer when we use timed activities in the room and I can ring the doorbell to change stations. It has work really well in the classroom.
