Awesome quality glow balls
Color: I) 8-Pack (2.5" Balls)
I have bought every glow ball on amazon many times over for my german shepherds. My longest lasting balls have been the chuck-it, they seem to glow longer and not get destroyed but are expensive. These glow balls are our new favorite and not only because of the low price. They hold a good glow longer are heavy duty and fit the chuck-it thrower perfectly. I am stocking up on these. Shipping was also next day so it's 100% buy on these.

Glow in the Dark Balls
Color: 2-Pack (3" Balls)
These balls are ok, not great. The reason they didn’t receive 5 stars is because they are hard/stiff, harder to throw & heavier than the the “Chuck It” glow in the dark balls. They did not hold up to heavy chewers as well as the aforementioned balls.

Light up and glow in the dark ball
Size: One-Size-for-Most
Definitely my girls favorite ball 😀. It disappears and I have to buy another one or she goes nuts. Glows in the dark, brighter with more sun. The bounce light up don’t last a real long time, too quick to quit for her but still loves it.

Durable & Bright - Great for Heavy Chewers
Size: One-Size-for-Most
Pros: Extremely Durable: Survived an aggressive chewer where tennis balls failed. Dual-Visibility: Features both internal flashing lights and a glow-in-the-dark "chargeable" surface. Perfect Size: Fits comfortably in the mouth of a 40lb medium-sized dog. Same size as a tennis ball. Cons: Battery Life: Unsure how long the internal flashing lights will last (though it has held up well so far).

Great for night time play!
Size: One-Size-for-Most
This ball is great! It is a 2-for-one light up feature so we love the flashing lights and if she drops it in the snow after those lights stop, we can still find it because of the strong glow that gets its charge from the flashing LED lights. Our first one lasted a few years, we lost it on a trip so now back for our second one so we can keep the night time fetch going! She is a golden retriever for size reference. Any bigger of a breed and I would worry it might be too small for her mouth. It’s a bit smaller than a tennis ball. Just don’t make the same mistake I did and let them have it in the house at night, she walked up to my bedside while I was asleep one night and squeezed it to activate it. Those lights are so bright it was a rude awakening!
