Captain loves it
So much easier to throw the ball. Pair with the three set of chuck-it balls. My parents can finally throw it far again

Great for my small dog.
My dog love's playing fetch. Keeps hands from getting dirty. Can bounce ball higher off the ground.

Too small
I was expecting a smaller ball launcher that would still launch regular size tennis balls. Nope

Wrong size
The description said that the chucker was compatible for regular size tennis balls, but it is only for smaller balls. So I never used it, returned to find a larger size.
