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.

These are cheaply made, and garbage, highly dangerous letting a dog chew on a battery pack
Color: Grid Pattern
These units are garbage. I got one for each of my dogs charged it up turned it on put it inside the rubberized ball shell and securely fastened it less than two minutes later my dog had taken it apart by just biting it and then started to chew on the battery and motor unit. So if you wanna have a lithium polymer fire in your house and potentially kill your animal, go ahead and get this, but if you do not want a fire in your house and you want your animal to live then absolutely do not buy this garbage it’s cheap we made and it’s not strong enough for any dog

Good Product, but images over promise just a little.
Color: Ripple Pattern
- Performs well on tile and low pile carpet. On artificial grass it doesn’t roll even on the highest setting; it only vibrates. Watch the video.
- Still fun for my pup. I’ve only had it a day so no clue about durability although my dog is a strong chewer.
- Price Value: When purchased it was 2 balls for the same price of a single ball from competitor.
- Material feels like a Nerf football. Easy to disassemble and charge.
