It's cool that yours glow, but my ESP Glo MJ Comets don't glow even a little bit. I wouldn't buy one expecting it to glow.Can only speak for myself, I have found Glo Comets to be discs short on dome, glide and stability.
No doubt there are exceptions and even Glo Comets have their place, but that is my observation.
When I want a glowing Comet, I use the ESP Glo MJ Signature discs. They are reasonably bright at night and glide forever. High dome and probably the most stable Comet everrrrrr.
