Great product and fast shipping
Style: EcoFetch
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!
Size: Medium
Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.
