Knock Knock. Who's there? You don't know. You don't know who? You don't know who's at your door because you can't actually hear them knocking. (See what we did there). It's true! Sometimes that doorbell just isn't loud enough or you can't hear knocking when you're not by the door. So, what's the solution? The Knock Knock Wireless Door Chime. This sensor and receiver set automatically chimes when someone is knocking at your door, alerting you to their arrival. To use, simply attach the sensor to the door using either double sided tape or screws. The sensor will then activate whenever it feels a knocking vibration. The receiver, which has a 100ft connectivity, will then chime in order to alert you to guests! Now you'll never miss another visitor, even if you're all the way in the back of your home or office.
