Fun dog toy!
First, I was impressedby the quality of this ball. It seems quite well made. The adult twists it open, it's tight enough I know my dog cannot open it. Note - there are warnings it is dangerous for a dog to get to the inside. That noted, I would always supervise. There are two choices of modes, one more intense. Hold to activate your choice and tightly put back together. It worked right away, vibrating and shaking. The humans greatly enjoyed, especially a child. My dog, a bit fearful but curious. So we will slowly introduce to her. The is a USB cord included for charging, which is nice. Overall a fun item!

Fun
Great product and works as advertised. My dog is small and was not that interested in it, but my black Labrador was all about it. Simple to use and easy to charge. It’s durable and has lasted against my lab so far.

My kitten loves this ball
I originally got this for my 14-year-old dog because he has always loved balls, and I thought it might be a fun way to provide a little extra stimulation and entertainment. Unfortunately, he didn’t show much interest in it. However, I honestly think that may have had more to do with his age than the toy itself. The surprise was my kitten. She absolutely loved it and spent quite a bit of time chasing, batting, and interacting with it. Once she figured out that touching it would make it move, it really seemed to hold her attention. I mainly used the passive mode, where the toy only moves after being touched. I liked this setting because it felt less overwhelming and encouraged interaction without constantly running around on its own. Based on my experience, I think this toy is best suited for younger, curious pets that enjoy investigating moving objects. While it wasn’t a hit with my senior dog, it was definitely a success with my kitten. Overall, it seems well made, easy to use, and a fun option for playful pets.
