The dog loves it. But.....the dog bites and twists it in his paws and is able to unscrew it. Now the threads are getting stripped. And I am concerned he will start chewing on the battery if I am not watching him. Update - the seller refunded my money, so all good. If your dog can't unscrew it, they will love it.

Not for my kids

Scary ball to my dogs. The power button is inside so you have to unscrew it, turn it on & screw it back together before it starts moving. It's not easy. It's harder than a rubber ball so I think it would be sturdy. It might work for some dogs, but mine ran for the hills!

High Priced Junk ! Don’t Purchase !!

Color: Blue

This is junk !!! Had it about 10 minutes till it stopped working !!!! Made cheap ! When my dog picked it up and dropped it from about 8-10 inches from the floor, it splits apart and kept doing that ! Also the inside part stopped working after the 1st time ! Warning ! This is very cheaply made ! For the price I thought it would be a good product. This proved me wrong !
