As I as was talking about this gadget, I could see the chatroom's dislike for it. The gadget? Fan Hands!
Want to make noise at a sport's event? Want to show that you're the "Ultimate Fan"? Fan Hands is a pair of specially designed gloves that have hard plastic pieces adhered to the palms and fingers. This enables the user to create a higher sound level than simply clapping their hands. They're still around and cost anywhere from about $7 to $20, depending on the color you choose.
The most hated gadget from Giz Wiz fan Kithron was the pest bug light from Amazon. His fell apart and luckily he was able to get this money back. The bug light half of mine stopped working, but it was too late to get a refund. It's still on Amazon, but price has dropped for $20 to $15.00. But I would think twice (or more times) before buying one. You can check the other reviews which seem to have gotten worse over time.
