Improve you basketball game by swapping your regular ball with the Evo One. It's a standard regulation basketball with a micro-sensor inside that emits sound that basically tells you how well you're doing on your free throws. It acts like a coach and trains you how “right” feels like by emitting an audible sound when the ball does a backspin of about 2 revolutions per second in a free throw. This is the optimum backspin rate that reduces the balls speed when it hits the rim making it more likely to drop in the rim.
