I love this thing. It's super well made and It enables me to chuck a ball the entire length of the dog park (I'm a 65 yr old woman with a wimpy arm). My dog is thrilled too. At first I thought it might be too heavy, but that's just not an issue, the weight is fine. For non-throwers like me someone at the dog park gave me a tip --- just look at the area you want to throw the ball. Helped my aim immensely. The 2.5 inch chuck it ball it comes with is my dog's absolute *favorite* . . . it's her security blanket in the kennel while driving, and it's her favorite ball to chase (the only one she'll actually bring back). She loves to chew it and to squish the air out of it, which takes a little effort. Recommend.
