EDIT: SO I READ OTHER REVIEWS THAT STATED IT NEEDS TO BE CHARGED BEFORE IT GLOWS, SO I WILL TRY THIS AND UPDATE MY REVIEW LATER...

It doesn't glow in the dark AT ALL. They show it glowing a blue color in the picture, but its just white/clear behind the cheap metal exterior.  I tried holding it to a light before stepping in to an unlit bathroom... and nothing happened, not even a faint luminescence. I will try to get a refund immediately.
