It stopped working after three play sessions
Size: One-Size-for-Most
I thought this ball was great until a week later it stopped blinking and got lost in the snow. We only played with it for three days for 20 minutes at a time. It should’ve lasted a lot longer.

It’s absolutely perfect for fetch in the dark!
Size: One-Size-for-Most
We needed to find a glow in the dark ball to run our over active dog after dark ( gets dark now about 5 pm ish) I was hesitant to buy this ball at first. We went to try it out and it totally blew my expectations! The ball really glows, it’s a durable rubber and when it hits the ground it lights up blue and red. Incredibly satisfied and just ordered 2 more. If you need to run your dog in the dark, this is absolutely for you. Highly recommend it

Dog loved it
Size: One-Size-for-Most
Great! My dog loves taking it outside at night so he can see where it goes easier. Super bouncy, he has had it for over a year now and still not destroyed. Perfect size for his mouth too and easy to clean.

Most durable one yet and it lights up. Our dog loves it.
Our dog destroys every other ball we've tried but this brand. I like the upgrade of being able to recharge it. She's a whole different dog when it's lit up. We're on her 4th one now and so far she hasn't torn any of them up. The ones with that were AA batteries always shorted out.

Best disco ball!
Had the old version of these balls that had batteries you actually replaced. This one is much better because you plug it in. My dog always loved this ball, because it's soft enough that she can take it in her mouth. And I love the color change. I got one for my daughter and her dog too, because I knew he loved them too.
