I wanted it to be a good fit
Color: Red
This toy garnered my dogs attention for a day. We tried it inside but there's too many places it would go under. We tried ot outside and it was powerful enough in the grass so tried concrete patio. My dog lost interest sadly. It wasn't a good product for my dog.

My pup loved it.
Color: Red
“Bought this for my dog Loki and it was an instant hit. He usually loses interest in toys pretty quickly, but this ball kept him entertained way longer than expected. The lights and movement immediately grabbed his attention, and he spent a solid hour chasing, pawing, and carrying it around the house.
It’s durable enough for excited play, easy to charge/use, and even survived Loki’s dramatic ‘victory laps’ through the living room. Bonus: it tired him out enough for an actual nap afterward. Definitely worth it for high-energy dogs or curious pets.”

Great toy to occupy pet
Color: Red, Color: Red
This ball is super fast, and lasts very long on one charge. It really keeps my cat entertained, he’s just so curious about it. It’s easy to pick out dust any hair it might catch on, it’s rubber material is durable. It’s a stable toy since my cat likes to play roughly.

Great for Puppies!
Color: Red
This toy has been a great purchase for my new puppy! He has so much fun playing with it and stays engaged for long periods. While it can move a little fast at first, the adjustable speed settings make it easy to customize. Overall, it’s a fantastic toy that keeps him active, entertained, and happy.

Good for (non-destructive) small dogs
Color: Red
Bought for a small dog, would not recommend for a destructive chewer. After some initial hesitation this has become her favorite toy and keeps her entertained for a good while. The different settings provide some variety to how she can play with it. The battery only lasts about an hour, but it does charge quickly. As others have noted the string is garbage.
