I gave this 4/5 stars because the ball is a little small for my dog size so I was hoping the sizing was easier to read. It could have been an error on my end. The ball is great though! It lights up nicely when it is out in the sunlight or under a light for a long periods of time, it lights up at night so you can play with your dog at night when it is cooler!

Well designed, well built.

The stick facilitates powerful, long distance throws. The ball makes a light whistling noise (to help your dog track the ball) through the air, flys far, and has held up well. I live in an area with mountain lions, and they often hunt at night, so I haven’t taken advantage of the glow-in-the-dark feature.

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.
