My dog loves this ball
Color: Green
The battery on this lasts forever. The random on/off motion and when it gets touched inducing motion just keeps my dog guessing and occupied for a long time. My dog's tail is wagging the whole time.

Great ball
I have bought two of these in different colors. My Yorkie loves them. They’re very interactive even if you don’t put the cover on it they move and if he’s not playing with it, it tends to go into sleep mode.My Yorkie got the cover off the ball within the first two minutes. But he loves the ball. Now bought 2nd ball. The ones with covers don’t work he rips the covers off.

Super Fun
Color: Green
One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too.
I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

Great customer service
Bought this for our dog for Christmas! He loved it! It sadly stopped working shortly after. Recently emailed the product site themselves and they sent a new one that week! Great customer service and great toy!!

Good product. My dog is very entertained and stimulated by playing with it.
Color: Green, Size: Small (2.0 in, Pack of 2)
I'M AMENDING THIS REVIEW AND ADJUSTING THE RATING UPWARD! Though it took my dog a little while to adjust to how differently this ball behaves, HE LOVES IT NOW. I wish I could give you a sense of how enjoyable and comically entertaining it is to play with him using it. ORIG. REVIEW: Bought this for a little 8 lb. aggressive chewer who loves to play fetch. I initially bought the 2" Chuckit! Ultra ball previously. It is the most amazingly durable product I've found for this pup. Very firm, but not hard on his teeth. He's very quick and agile, so I thought he would like the eye-mouth coordination challenge of a ball that changes direction suddenly. I guess my only disappointment with the product is that the ball is hollow instead of having a solid core like the Ultra ball, so he doesn't enjoy chomping down on it the same way. The erratic bounce feature is entertaining, but the pup is a little skittish, so he was intimidated at first. He's warmed up to it, but not with the same enthusiasm as the Ultra ball. Having said all this, I don't fault the product for the rating I gave it. It is a quality-made product that performs as advertised. I just didn't anticipate that my dog would be less enthusiastic than I thought.
