This is an awesome toy!! After the freshly charged glow fades, it still has enough oomph left for Molly to find it in the dark. She LOVES this frisbee! In fact, I woke in the middle of the night to find this faintly glowing round thing on the end of our bed....thought maybe a UFO? Little green alien maybe?? Nope! It was her favorite friz, still going!!! Beside that, when you toss it, it really flies a long way. We have two of these, just in case. I wouldn't want to be caught without one, for sure!! Get one (or two...)! Best toy ever!!!
