Instructions and charger included (not sure if original). Condition- Used but fully functional. Vapor Strobe trains your brain to react more quickly and accurately during sport, so you can perform better on game day. The eyewear uses an adjustable, electronic strobe effect to alternate the lenses between clear and blocked vision, forcing your brain to anticipate what is coming when your eyes are blocked. It's like swinging a weighted bat, then taking the weights off- except Vapor Strobe trains your brain, and then your muscles react.
When you improve your brain's response, you improve your performance, in all sports and all conditions.
