So far, I've really enjoyed using my glow frisbee!! I've used it to play two intense games of ultimate frisbee and it's worked very well both times. It's perfect for late night games because it's super bright and easy to see!! My only complaint is that the wiring isn't very durable. One of the light bulbs has already broken do to poor wiring. I think it's fixable but annoying that after two games it's already broken. Other then that, it's an awesome disk and I would highly suggest getting it ;) 5 stars
