Only vibrates...
Color: Blue
It only vibrates. My dog enjoys it, but it doesn't spin or do what you would expect it to do. I essentially bought my dog a vibrator...

Great dog toy
Color: Blue
My dog loves this interactive ball. It is made with great material and the quality is good. It is rechargeable and it's great to take to dog park and also out in my back yard. My dog enjoys it so much . The battery life is great and it is chew resistant. It don't make much noise and that's a good thing. Size is just right for my dog.

PUPPY APPROVES
Color: Orange
Fun interactive toy. I felt this was a little pricey but watching my puppy playing with it is priceless.
She flings it all over the room. As a puppy she chews on it a lot because of teething but there still isn’t a mark on it.
Battery lasts a very long time and requires no replacement batteries just a usb connection.
It is a little noisy so sometimes I let her play with it without turning it on.
All told, it is one of her favorite toys. She is 4 months and weighs 7 pounds, just to give you an idea if it will work for your dog.

Absolutely would buy again
Color: Orange
I love this, my pup loves this.
Strong, sturdy. Shakes all over the place.
Pup loves to chew on it, I think the vibration comforts her gums from teething.
Perfect size
You must take the outer skin off and pop open the white power button to charge it.
Total fun!
