This looked like a great idea for my energetic pup until I charged it and turned it on. It worked for maybe 3 minutes and she loved it while it was moving. It stopped suddenly and when I opened the Velcro to pull out the ball to check it, it was VERY warm. Unsafe for human or dog. For over $20 I would expect more for a dog toy. Cheap and non working! I will request a refund !
