Review on Reflex Reaction Accuracy Training Headband by Jason Chaplain

It's fun. I bought it for my kid who is 10 years old and does fitness and parkour. He wants to train and improve hand-eye coordination. I also think it's fun to play with him. It takes a little trial and error to figure out how long the cable should be. I think the cord should be measured from forehead to navel. It seems to me the most comfortable place. Great that there are so many types of balls and two different headbands. It's like I bought two sets in one! Young Sonny can do it and so can I!
