Happy puppy.
Color: Blue
My puppy loves his. He carry's it around and throws it. He knows how to turn it on himself. Charges quick.

Overall, I highly recommend it!”
Great toy! My dog loves it 🐶 The ball moves on its own and keeps him entertained for a long time. It’s perfect when I’m busy or not at home.
Good quality and fun, but maybe not the best for very aggressive chewers.

Puppy loves it but the battery is awful
Color: Blue
Our puppy loves playing with this ball, it does what it says and keeps her occupied for the entire 10-15 minutes the battery lasts. I have to charge it several times a day, though the light never flashes red when the battery is low, it just doesn't work anymore. It also makes a beeping sound when she's playing with it that is super annoying, which sucks because the ball itself isn't super noisy even in the hardwood floors. I wouldn't purchase this again, and we'll probably have to toss it out within a week or two, I really don't see this thing lasting very long. Without the movement, it isn't a ball we would let her play with because she is a strong chewer and the material doesn't seem chew proof at all. I'm only giving it 2 stars because she really does love playing with it, but the battery life and beeping sound are atrocious.
