Love these Chuckits!
These are awesome. Haven't broke one yet and the puppy loves it and so does my arm! Doesn't hurt to cast it out. Yay me!

No returns… Confusing description
The seller doesn’t allow returns with this product. This product was much smaller than I expected, and I wouldn’t even re-gift it to a friend with a smaller dog. Why? Because they already tried a similar size and said it kept their hands clean… but gave them tennis elbow.

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