LOVE IT LOVE IT LOVE IT!  My young doberman needs a LOT of exercise and this toy really helps.  I can throw the ball at least 3 times farther and he love racing after it full speed.  There is the added benefit of being able to scoop the ball off the ground (I taught him to "Drop it") and not have to pick up muddy, slimy, icy balls with my hand.  On these dark winter days I can get close to wearing him out in just 20 minutes.  We may have to invest in one of the glow-in-the-dark versions.  Well worth the money!
