Very firstly when I looked at the pic, I was a bit confused that how will it work. As the picture doesn’t reveal much, the video will really help you out in making your concept clear about weird looking Wii accessory.

Wii accessory is ThinkGeek’s WiiHelm that requires no hands for playing games on your Wii console. The controller scheme is pretty good as you can play games without using your hands because the specially designed Helmet does it all. The helmet can hold your Wii-mote and you can have a long gaming session with WiiHelm.

Key Features:

• Effortless handsfree gameplay

• Good compatibility with Wii-Sports and all your favorite Wii games

• 4 LEDs at frontage to light up your surrounding

• Included Foot Pedals with all Wii-mote Buttons, mapped to strategic toe areas

• ThinkGeek’s new WiiHelm comes with Foot pedals, Cables and 1 year Warranty

The accessory doesn’t impress me much since for how long could you wave your head to strike pins in Wii Bowling or hit the ball hard to make it soar in the hair for many seconds in Wii-Baseball. It could be dangerous to your neck muscle, somehow, because you need to wave your neck consistently and could make you feel giddy after some time resulting in some sever problem.

So, if you think WiiHelm a cheap alternative to save your thousands of dollars in damaged flat-screen TV, then I would suggest you to think again...!
