QBall Reaction Ball

These balls are an interesting eye-hand coordination training tool that I received at a discount in exchange for my unbiased review.

I received a set of two of these training balls. They are made of solid rubber, and are fairly dense. They certainly seem well-made.

There are a variety of exercises these balls can be used for. The company that produces these balls has an entire section of their website dedicated to explaining these exercises, and how using these balls can improve your eye-hand coordination, your reaction time, and your focus, among other things. You can also find videos demonstrating how the balls may be used.

I have not used the balls enough myself to be able to say whether or not the company's claims are true, but I can say that I have enjoyed practicing with the balls. The exercise that I like, and have attempted several times, involves bouncing a ball from about waist height alternately with each hand, so you are bouncing two balls in quick succession--one with each hand. The idea is to see how many bounces you can accomplish in a minute. Because the balls are not perfectly round--they have dimples or divots on them--the balls do not bounce in a perfectly true fashion, meaning you have to work a bit to catch them.

I've always thought that I have better than average eye-hand coordination, and my minimal experiments with these balls bear that out. The first time I attempted this exercise I successfully bounced the balls 86 times. Since then I quickly improved to the point where I'd pretty easily reach the 90s, and my best score (out of perhaps 15-20 attempts) is 104 catches in a minute. By comparison, my wife and adult daughters each achieved a best score, after a few attempts, of 74, 56, and 47. (I won't embarrass them by being more specific than that.)

I have no reason to doubt the company's claims that regular exercise with these balls would improve eye-hand coordination, focus, etc. The balls are fun to use, though the exercises do get a bit tedious after a while. If you're willing to spend some time training, I think these balls are probably worth purchasing. They are relatively inexpensive, and should last a long time.
