Nite Ize makes great products. I especially like the extended time the ball stays lit. Especially for those times the dog decides not to retrieve and you're searching the ground for the ball in the dark. It's heavy. Good for power chewers. Not a lot of bounce but then again the light function is the primary goal.

Stopped working the 2nd day

I realize I am the minority. This ball has great reviews. So it has to just be my bad luck. But it worked great the 1st day. Had some problems with getting it to turn on the next day. After that it never came on again. I bought new batteries and put 2 new batteries in it. It still did not light up. Other than that, it’s great and seems durable. I just can’t get the lights to work on it.

Very durable and my dog loves it.

This is a great ball for the dog. It is very durable and has led light inside. Easy for me to throw and great for playing with my dog. No noise just the lights. What a great value. Even the smaller dogs can play with this one. Smaller and lighter .
