The value of a good flashlight is underrated. And one that's small enough to fit on your keyring while still packing some real brightness is all the more rare. The next time you drop a tiny screw or need to take a peek under the hood of your vehicle in the middle of the night, your life will be much easier if you've got MecArmy's IllumineX-4S. Packing a 130-lumen maximum output into an anodized aluminum flashlight that's about the size of a AAA battery and can be attached to your keychain is impressive. Add on the fact that this one is rechargeable via micro USB in only an hour, and it's an EDC must-have.
Easy to set up. Came fully charged. Hi and lo settings, hi very bright. Twist switch can't go on accidentally, which is why I got rid of my old pocket flashlight. Can't speak to run time. On my wife's and my key chains now.
