You can barely whip it and it sails far and fast. This is the perfect retrieving toy for my GSP. She's used to average and we now have a small yard, so the dog park is where she gets to run hard and fast. You can also throw tennis balls with it, which is a plus for when her sister steals her ball. 5 star fun!

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.

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!
