Nite Ize just can't get this figured out. This ball is by far my dogs favorite ball. We play ball daily, and when we don't get in a ball session during the day, we pull one of these out after dark. The problem persists even on the new rechargeable design. They just don't last. With the old battery operated version we just knew we would spend the 25 or so dollars each month to purchase a new one as the light mechanism would fail. When they updated to the rechargeable version I was ecstatic to try it. I bought one and it lasted an entire month before we lost it over a fence. I purchased a replacement thinking that Nite Ize finally figured out the design. I was wrong, this one lasted for about 6 or 7 evenings of ball fetching and stopped working. Just a disappointment that they can't get this issue solved.

Doggy and Daddy like the pretty lights

My dog loves this ball! So do his friends. He's not much of a ball guy during the day, but loses his mind with this ball. And I like it because the pretty changy colors agree with my edibles. Very durable and the charge seems to last at least five hours.

My dog loves them

Love them but wish they were a bit more durable. The bounce high, fit the thrower and they don’t weight too much. A little steep on price but the dog loves them

EXCELLENT PRODUCT!!!!!

If I could give it 10 stars, I would. This ball is AMAZING! Love that it's rechargeable, that it shuts off after 10 minutes of inactivity, that it changes colors. It's dark by the time I get home from work so playing ball in the dark with this ball is a game changer.
