Works great with tennis balls
I have a pretty large yard, and this thrower is great for my little Jack Russel puppy. It even picks up ball without having to touch all the spit.

Thing is absolutely garbage. Ball didn’t make it back once! Broke in half
Junk and they don’t follow through with the shipping that they claim. Said between 7am and 11am. Don’t post it if ya can’t fulfill your shipping expectations

Good toy for dogs
This is a great toy! I do wish the handle was a little longer because I do not have a lot of upper body strength due to health issues. I can still throw with this further than I can without the launcher so my dogs really love it and get excited any time I get this out!
