BUY IT!!
Color: Blue Dog Ball Launcher, Size: One-Size
Great product!! Releases the ball nicely and saves my arm from dying at the end of the day. The construction of it feels flimsy but for someone who uses it AT LEAST 3 hours EVERYDAY, I would say it's pretty good quality. Would highly recommend!!

Fantastic tool for dog owners!
Size: 1-pack
This is a great tool to keep your dog active without getting your hands messy! I discovered it launches better when you don't push the ball completely into the holder, but just have it in partially. The ball included is nice and bouncy. The launcher also works with Kong balls.

Endless Fetch Fun—Perfect for My Jack Russell!
Size: 1-pack
This ball launcher has been a total game-changer for fetch time with my Jack Russell! She has tons of energy, and this helps me keep up without wearing out my arm. It works great with most standard tennis balls, so I don’t have to worry about tracking down special ones.

It is good for small yards but not so good for distance.
Size: 1-pack
Getting used to a ball thrower takes practice. This one is no exception. The angle is off for me. If I use it as an extension of my arm it goes straight to the ground, but once I got the hang of it. Balls launch with great height. Distance isn't a feature for this tool.

Get a longer launcher. This only throws 30 ft
Size: 1+3pack
Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.
