Great product and fast shipping

Great ball launcher and ball. My dog adores it and plays with the ball even when she isn’t fetching. Fast shipping as well!

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.

Yes!

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.
