Lil boy's favorite ball
Style: Recharges, Size: Medium
The squeak gets my little boy every time. The glow factor is under par. I mainly get it because he also enjoys the brighter colors. All of the others be trying to get his ball. Good product just wish it would glow better because our park times are right around sunset.

The glow doesn’t last long, not super bright.
Style: Recharges, Size: Medium
I charge my glow in the dark balls with a black light flashlight, this one was not very bright, and it did not hold the charge very long. Also, with it being green, it was hard for my dog to find in the grass.
