This is a cool little light. It's lightweight and fits nicely in the palm of my hand. It's fun and easy to 'rev-up' the battery. It's bright enough for a night time hike and you don't have to worry about the batteries. I can tell you from experience that it's scary to be in the middle of the dark woods with cactus all around when your flashlight dies!

Cool product. We'll give these away as a gift. The technology is cool!

These really are great. I cranked it for one minute and left it on - it was still going strong after 2 1/2 hours. Bright light, lightweight.
