I have two border collies and if you have ever been around one, you know that they have a lot of energy. In the past I could throw the tennis ball at least 20 times and they just begin to get tired. With this device, I can throw the ball over 100 yards and after 20 times, they are panting hard and wanting more (they love this game sooooo much), and will start to slow down.

Great way for your dogs to get exercise and your arm does not get tired.

Pros: Easy to throw a tennis ball very far

Cons: Your arm is going to wear out before the dog

I have used these at a dog park I go to. Throws balls real far, far enough to loose some. Only works with smaller balls.

Pros: Throws balls real far

Cons: Doesn't work with regular T.balls

Cons: not eaisy to pack

This is great for dogs that like to fetch. Sometimes it really throws it pretty far though. Perfect for retrievers!
