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.

Dog hasn’t destroyed the ball yet!
The ball that comes with this is amazing. I have a 1 yr pitty that destroys everything! But this ball she has not been able to rip apart. I bought extra balls I was so impressed. She loves it too, takes it to bed with her.lol
