It is durable! Lights still working after a month of use
This is the first ball that my dog hasn’t been able to break the lights!

Keep your dog active for hours
Color: Classic, Size: M 3.46 in (8.8 cm)
I buy 2 of these balls a month. My Boston Terrier is obsessed and rolls the ball for hours. It is made of a hard plastic so it is best to play with it outside.

Great for dogs
Color: Classic, Size: XS 2.75 in (7 cm)
Puppies and dogs love this. I have a bigger one as well so I wanted one they could fetch. This works perfectly for fetch.

Total waste of money
Color: Classic, Size: L 3.94 in (10 cm)
I seldom write reviews, but save your money as far as I’m concerned. Maybe mine was faulty. I don’t know. But it’s hard as a rock and too big for to my Australian Shepherd to get her teeth around. It barely made a noise. Maybe I misunderstood the description, but I bought it for her because she’s blind and yet loves to play fetch so I thought it was going to make enough noise for her to find it, but it was a total bust at least for me.
