Easy to use for this old folk!
Style: EcoFetch
If you have a hard time to bend down and throw, this is perfect! It allows you to pick up the ball with little bending over. It also gives much further distance to your throws. Great quality to both the ball and wand.

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.
