This wireless remote doorbell is awesome! You just plug the reciever into the wall plug and the doorbell is attached outside by the door. When you push the doorbell it rings in the house! How convienient is that? I love it. Now I can hear it even when I am not in that same room. No more missing people because I didn't hear them knocking on the door. I have wanted to try one out for a while, and was very excited to find this one. this wireless doorbell is classy looking and woorks great! It is waterproof so being out side will not hurt it. I am very happy to have this!
