I bought it because I was looking for a rechargeable light, and it's great in that aspect: built-in USB, plugs into computer, no cables, and it even lasts for a very long time. Wet conditions haven't been a problem either. It's got a pretty good design, too; easy to put on and take off, compact, and cool to have. It's not very bright though; I wouldn't call it "wicked bright" as they advertised. It's more than enough to be visible when it's dark or foggy, but it doesn't light up your path very well.
