Yep, lots of people fall for it easily. A friend of mine actually bought the clapper when it first came out. She said that was a worthless piece of device. However, I did see one device that is related to the clapper. This device has been making rounds in the infomercial channels. It's an adapter that goes between your mains plug (power plug) and your lamp. It comes with a wireless remote control (it looks like a light switch) that allows you to "cut" power off from your lamp. It reminds me of Zigbee devices. Although, I don't think it uses that protocol because Zigbee devices are supposed to be able to form networks with each other.
