This product is oddly weird, but looks so useful. From the video, this can definitely change the way we use our hands. Instead of needing both hands to grasp things, we now only need one. I can't begin to imagine the possibilities.
It's very out of the box thinking from a design standpoint, as well. And the idea of using prosthetics to extend and improve on the human body, not just to "fix" a perceived disability, is something I find very interesting too. What's next? An extra limb? Really cool find!
