At CES 2013, mc10 and Reebok revealed the Checklight, a product built to help protect athletes who play football, hockey and other impact sports. Today, you can purchase one of your very own in men's, women's or children's sizes for $149.99 from Reebok's website. For your money, you get the sensor strip, a skull cap to keep it snug on your noggin and a micro-USB charger to keep it powered up.
For those who've forgotten, the Checklight's a head impact indicator powered by mc10's flexible electronics technology that gives athletes and medical personnel simple, actionable information about impacts to the wearer's head. It's not a concussion detector, per se, but it does provide information about the location, number and intensity of impacts to your dome -- so it's a valuable tool that can help identify those in danger and keep them out of harm's way. Well worth $150, we'd say.
