Best jiggle balls we have found thus far
Color: Ripple Pattern
Yes ! First off this was a great value for the money. The balls function just as described and they have a decent battery life. They entertain both our goldens for a good bit of time. They have so far held up and not been chewed up . We limit the time and put them away after that time.. to avoid them being destroyed. Of all the jiggle balls we have purchased these are by far the best. The way the component is encased in the rubber protects it.. and it screws together very well. I am so pleased with these !

Highly recommend for pet owners looking to keep their dogs busy and happy!
Color: Grid Pattern
These interactive dog toys were a great surprise! My dog was instantly interested in the bouncing and vibrating movement, and it kept him entertained much longer than regular toys. I like that the balls are rechargeable and washable, which makes them easy to maintain after outdoor play. The automatic motion is fun and unpredictable enough to keep pets curious and active. Great value for a 2-pack, especially for energetic dogs that need extra stimulation during the day. Highly recommend for pet owners looking to keep their dogs busy and happy!

Must have for your doggy!
Color: Grid Pattern
This interactive dog toy ball is amazing! It moves and jumps automatically, which keeps my dog constantly engaged and excited. My dog loves chasing it around the house and never seems to get bored. The material feels very durable and holds up well even with strong chewing. It’s a great way to keep pets active and entertained. Definitely a fun and high-quality toy I would recommend!

Not a Tough Chew Toy for Large Dogs
Color: Grid Pattern
While these were quite entertaining for our golden retrievers, they lasted only about 30 minutes before they were destroyed. This is NOT a tough toy item.
