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!
