The Clapper plugs into a U.S.-type electrical outlet, and allows control of up to two devices plugged into the Clapper.[3] An upgraded model, known as the Clapper Plus, includes a remote control function in addition to the original sound-based activation.[4]
Although meant to activate by clapping, The Clapper can inadvertently be triggered by other noises like dogs barking for example.[5]
