My Rottweiler loves it!
My Rottie plays with this for hours at a time! He loves it! It fun to watch too! The plastic is high quality and has lasted for 2 weeks, so far. That pretty good for a Rottie toy! He loves the lights, vibration, and the fact that it rolls away. So fun!

Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.

Fun and durable toy
Lots of fun for this crazy guy! He pounces on it, chases it and has so much fun. The confusion on his face is so funny. He usually gets bored fast, however this ball keeps him quite entertained. The ball holds a charge for a few playtimes so that is also a plus!
