UPGRADED VERSION - Based on valuable customer feedback, we have improved the product and are proud to introduce the YMX BOXING V2.0 Reflex Ball. The new version includes 2 comfortable headbands and 2 beginner training balls, allowing two people to train together, along with 2 advanced-level balls for more challenging workouts. THE BEST WAY TO GET OFF VIDEO GAMES AND STAY ACTIVE - My 10- and 12-year-olds love it so much that I came back to order several more as birthday gifts for their friends. My husband uses my sons' set so much that I think I'll need to get another one for our household. Best of all, it gets kids off gaming devices and moving around—on their own initiative. FUN FOR THE WHOLE FAMILY - Children aged 8 and up, as well as adults up to age 70+, enjoy this engaging and competitive game. Everyone tries to beat each other by achieving more consecutive hits. GREAT WORKOUT WITHOUT NOTICING - Reflex balls are the modern alternative for those who enjoy fun activities while getting exercise. With a high fun factor and a gentle learning curve, the experience is surprisingly addictive. Time flies, and you don’t even realize how much you’ve worked out. THE BEST WAY TO IMPROVE REACTION TIME & HAND-EYE COORDINATION - While it may not improve boxing technique, it effectively enhances reaction time and hand-eye coordination, making it an excellent choice for fun warm-up exercises.
