Clap off to join the Dark Side! For the first time ever, The Clapper joins with Star Wars! Let the power of The Force control your appliances, and hear the voice of Darth Vader. Plug a lamp or other device into the Clapper and turn it on and off with a simple clap of your hands. You'll hear a Darth Vader quote each time to indicate your command has been received. Clap on: "The Force is strong with this one." Clap off: "You underestimate the power of the Dark Side." The Clapper is sculpted in the shape of Darth Vader's head.
