Testing Reebok's Checklight head impact monitor with a human punching bagLast year Reebok showed up to CES with the Checklight, a head impact sensor developed in collaboration with mc10. Problem was, the company didn't really have way to demo the preproduction version of its G-force sensor. They simply slipped it into a black skull cap and let the press take photos. But, in the interim, it's come to market, offering protection to athletes young and old, for a reasonably affordable $149.
