This is the greatest invention since the ball. Anyone can throw the ball major distances with little effort. Saves the old arm muscles. Our Lab, Belle, loves it. She loves to play ball and could go for hours. We get tired long before she does. But with the chuck it we can keep up with her. (well almost). Great product, sturdy, easy to use, fair price. I would definitely recommend this product if you have a dog that loves to play fetch.
