Great keychain light
This replaced a 3 button cell light on my keychain. It's perhaps half as long again, but feels no bigger in the pocket, but wow, what a difference! In full power mode, it's as bright as my mini Maglite LED, and lasts just as long. In low power, it's often bright enough, and lasts for hours! I love the copper finish... a couple of moths in and it's startung to patina up well. I think I'd have preferred brass, but that wasn't in stock at the time... maybe a second one?
