My dog absolutely loves this toy! The bouncing and vibrating motion keeps him entertained for a long time and helps burn off energy. The material feels durable and holds up well even with aggressive chewing. I also like that it’s rechargeable and easy to use. Great interactive toy for keeping dogs active and busy — definitely worth the purchase!

Fun dog toy.

Loads of fun for my dog, but sometimes un-entertaining. It just bounces around the floor.

The price, the quality

This is exactly what my puppy needed to keep himself entertained. He gets really excited when it vibrates and chases after it. It’s made of good material, and you don’t have to open the lid to turn it on, which makes it much easier to switch on. I highly recommend it I would definitely buy it again.

Lasted 2 whole minutes

I think the foam should be thicker because my 1 yr old rottweiler puppy bit the ball where it closes/screws together and the plastic threading crumbled. Might be better for smaller puppies/dogs or cats, but for me it's 👎

Not worth the money.

Don't waste your money on this item, it is not as shown and described. Smaller than it looks and doesn't move as depicted.
