Probably one of the best purchases I have made! The balls are far superior to any tennis ball. My dog likes to chew or bite down on the balls once she catches them and tennis balls ball apart. As to the actual thrower - the extra length on this one has helped me, I had back surgery and am not able to bend over I can reach the ball without too much difficulty. So to sum it up - best dog throwing toy I have purchase!
