Query: Chucket Ball Launcher

I first saw a Chuckit! Ball Launcher at our local off-leash dog park. My 81 year-old elbow can't stand as much throwing as my energetic dog wants, and needs. I bought the short, pocket size, launcher so that we could play ball in my back yard. The full size launcher is capable of launching a ball much further than the pocket model. It works perfectly, throwing a standard tennis ball without straining my old arm. An excellent product!
