Price Paid: $13
The Fenix E01 is the best AAA 10-lumen key-chain flashlight for the money, outshining all others that retail for less than $25. It is perfect for illuminating keyholes, locating your seat in a movie theater or finding that elusive guitar pick that was thrown right at your feet by Robin Zander of Cheap Trick. It's also nice for close-up work behind your computer in hard to reach places.
Don't leave home without it, because the best flashlight is the one that you have in your pocket, not the one that has been left in the car or at home.
