Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

These are dog tested and approved.

The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

No angle for correct throwing

Size: 1-pack, Size: 1-pack

This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend
