The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

No angle for correct throwing

This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend

Happy pup. Worth it.

My dog loves this thing. It takes hardly any effort to launch the ball. Flick of the wrist kinda thing. The squeaky ball is her favorite but unfortunately you can't buy this brand of ball separately. It says compatible with any 2.5 inch ball but that's not true. We have a ton of Penn tennis balls and they are just slightly too big for this launcher. You can do it but it's a huge pain and hard to throw. Another issue is that when we first got it the handle didn't want to stay screwed together. After the first day of use and having to rescrew it together multiple times, the issue seems to have corrected itself? Either way, for the price with the comfy handle, very low effort throwing for big pay off, two balls included and the crazy excitement from my dog anytime we get near the thing. It's definitely worth it. I like it much better than the chuck it and stone random cheap brand we used to have. I'm going to try one of the balls recommended in the product pictures. I'll update if they work out.
