Ting tong doorbells are passe and those gongs are unmanageable…so what’s the latest in the door bell’s world. It is the Knock Knock Chime. This one is a unique concept that converts a knock on the door into tingling sound of a wind chime.
This happens with a wireless system, you just have to place a chime in your home and this one gets activated as soon as someone knocks at your door. Just mount the sensor behind the door and see that knock knock changing into soothing chime sound.
