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.

Was hopeful…
Was hoping this version would be better, but no. Welcome to the Nite Ize repair center. The pictures show the old version run by LED batteries. Although they claim the balls are waterproof, no. I’ve learned to clean out the contacts and add new batteries to reuse them, but a lot of the time the rust has already formed. The new rechargeable version is more expensive and has the same ‘waterproof’ casing. First charge was good; second charge didn’t even last for our retrieving sessions one evening. Third session on a full
Charge didn’t even last one session. Too much money for the quality. When they work - they are great. Unfortunately, still the best on the market, it it’s just like throwing away money. Innovators???
