Value for your money
Style: EcoFetch
It's definitely different from the one I lost. It's taking me some time how to throw the ball correctly. It's a hit and miss but we are getting there. When I do get a good throw, it really wings it out there.

Great quality and folding it in half is a plus. Fits under a seat in car/truck.
Purchased another, as we need one in each car. This is a great ball thrower, especially as it folds in a half. Makes it easy to store under a car/truck seat. Haven’t had any problem with it, great quality!

Fantastic throwing aid!
Very well made, great quality and doesn't feel cheap at all. It's thick, not flimsy or fragile so you can really swing it to launch a ball. Saves my body that I don't have to bend over to pick up the ball anymore, and saves my shoulder that I don't have to hurl the ball anymore. Another bonus is you don't have to touch a slobbered, soggy ball, or a ball covered in dirt. The foldable design is fantastic because I walk everywhere with my dog and don't want to carry around a long stick that's awkward to hold. This folds down small enough that I can securely put it in the back pocket of my jeans without worrying about it falling out. The thing I love most about it is there's a elastic loop at the end so when you fold it you can latch it securely. This small detail is outstanding because I can also hang it on the strap of my sling bag and with the loop secured it will not slip off the strap. This product is so well made and thought out overall.
