Unparalleled performance durability and the glow is incredible! I read the bad review on this product about how it doesn't glow. I don't know if they know that they have to expose it to light in order for it to start glowing but this thing is BRIGHT! Lights up and stores glow for about an hour or so then it starts to go out but I keep a flashlight on me when I'm playing in the dark just in case and I recharge it with my flashlight. Solid/awesome/backed with a 100% guarantee?! BUY THIS PRODUCT!
