Worth every cent
Color: Blue
My dog has chewed through so many heavy chewers toys but he loves this ball and he has not tried to bite through it. Keeps him busy 15-20 minutes

Pricey otherwise enjoyable
Color: Red
Ball is made of a durable type material kinda like a foam only not chewable, at least not yet
Very entertaining and has a whining noise, it does bounce a little bit and moves somewhat when nudged by dog. Bouncy. Not a very high bounce so it keeps close to ground. The ball was fully charged when it arrived and has entertained her for about an hour now that she has settled down so it did what I hoped it would do, to keep herself busy to the point of being tired. At best I would not leave this lying around for heavy chewing use only for entertainment or play time.

Mostly Good toy. Could be great.
Color: Blue
The ball looks well made and the dog absolutely loves it. He can't stop playing with it. It's awsome to see. The only problem, abd it's a big one, is that we can't open the ball to turn it off. The two halves are stuck together and don't budge. I'll wait until battery dies and try then.

Entertaining
Color: Blue
This smart ball is a great toy for your dog. It’s the perfect size for most dogs and it’s made of durable material that chewing doesn’t hurt. It’s easy to charge and will run for hours. It’s very quiet and has 3 modes of play to choose from, rolling, bouncing or a combination of both to keep them (and you) entertained for hours.

Color: Blue, Color: Blue
I bought this interactive ball for my dog, and it has been an excellent purchase. He loves playing with it because it moves and bounces on its own, keeping him entertained for a long time. It feels durable, is easy to charge, and is of very high quality. I would definitely recommend it to anyone looking for a fun, long-lasting toy for their pets.
