I can't believe how much I've enjoyed this keychain sized flashlight. I've had mine about a yr now and it's been great. I need to order a few more to stash around and to give as gifts. They charge via micro usb cable and are very bright (45 lumens on high) for the size and weight. It's not a tactical light but is plenty bright enough for any EDC utilitarian needs I've had. I use mine alot and with a once weekly charge I've never had it die. It's so light you'll never know you have it. It splits time on my keychain and in my watch pocket. Well worth the $10 price tag. Pictured here with my LM Squirt PS4 for size comparison.
