I purchased this dog toy hoping it would keep my dog entertained and engaged, but unfortunately, it has been a huge disappointment. The first one I received only worked for about an hour before completely stopping. I decided to give it another chance and ordered a second one, hoping it was just a fluke. Unfortunately, the second one lasted even shorter—only 30 minutes—before completely ceasing to function. It no longer vibrates, rotates, or interacts in any way. Even when fully charged, the toy barely lights up and doesn’t do anything useful. This is a terrible product, and I’m genuinely shocked by the positive reviews. Save your money—this toy is not worth it.

My dog loves it

My Aussie loves it and he is a tough chewer as well, so it goes great with his hyper reactive personality. Durability could have been a little better, sometimes I have to take it apart and make sure it’s still in a good position because my dog will pick it up and drop it. With no cushion it did start malfunctioning at about 2 weeks. However, it does still work fine and he loves it even without the movement. Note if you put it in a sock to protect it, my dog goes dangerous and held the sock and created a slingshot lol.

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.
