It launches balls impressively far, which keeps my pup happily running and burning off energy. No longer having to bend down to pick up slobbery tennis balls! is a huge win! It’s lightweight, easy to use, and surprisingly durable. Highly recommend for anyone with an energetic pup and a desire to keep fetch going without the strain! Just note that it is for smaller sized tennis balls.

Excellent product, but keep it away from chewers.

Style: 2.5" Ball

This is a very strong and effective launcher and could have lasted a very long time had my 9 month old not chewed the ball claw end off. I will buy again.
