A keychain flashlight's primary purpose is light-in-a-pinch. For getting to and fro your car in the dark. An unexpected walk in the dark and you just need to not trip. In other words, they should be designed to give 'just enough' light and have extended battery life so that the light is available when you need it. Short battery life means you'll more frequently turn on the light and have no light; and since you'll likely be in a pinch, it is especially bad. For example, a well known USA flashlight manufacturer has a keychain light that has one very bright level and, thus, very short battery life. For some in-a-pinch situations the brightness can actually be blinding and the very short battery life means the light will often be dead when you need. In other words, they made it too bright and less reliable (because the battery dies so often). However, Fenix's E01 V.2 is done right. Perfect actually—for five reasons. 1) It's default brightness is 5 lumens which is a very sufficient amount of light for in-a-pinch situations. For comparison, the keychain light I used for 20 years was 2 lumens--it was always 'just enough' light for not tripping, etc. 5 lumens is a fantastic amount of light without being bright. 2) The battery life at 5 lumens is over 20 hours. This is fantastic. You will very rarely hit a dead battery. 3) Light beam is quite floody. This is good because the primary purpose is for close up illumination such as lighting your way so you don't trip. A broader flood of light at your feet is much better than a bright little spot on the ground. 4) Fenix made 5 lumens the default brightness. There are many similar keychain lights (even Fenix has some) that make the second brightness level the default. This is problematic because it encourages battery draining and it's almost always more light than is needed in a pinch. Further, it encourages using the light for 'regular' flashlight needs because it's good amount of light which exacerbates the battery issue. Making the default level 5 lumens encourages using 'just enough' light and getting the long battery life that is important for a keychain light. 5) It's can be really bright if you need it! This is phenomenal. Need to see what's rustling in the bushes or the tree? You've got 100 lumens available to you! Obviously, if you use the brighter levels a lot, you'll get much, much shorter battery life, but it's awesome that you have that option. If you want a perfect keychain light--for light in a pinch--grab one of these!

3 brightness levels, although typically I only need to use the lowest (longest lasting) level. The highest/brightest level is surprising for such a bitty EDC (pocket/everyday carry) light. The twist-head ON/OFF switch works great and likely seals out water/debris better/longer/more reliably than a tailcap switch; however, that means I need two hands to turn it ON/OFF (versus one-handed with just my thumb), and cannot practically momentarily "blink" out, say, a SOS code or other reason for a quick flash. I'd prefer to skip the middle brightness level, and would prefer that it had a "firefly"/"moonlight" level instead. Also a SOS feature (or, less useful to me, a simple "strobe") would have been nice. But at this size, brightness and price it's still a fine and very useful flashlight -- recommended!

I love this thing! For such a tiny flashlight, it's very bright. Well-made an feels good in the hand. Only thing that is a bit cumbersome is that you have to rotate the top screw-in head back and forth to turn it on and off quickly to change brightness modes. It's a bit of a pain, but by doing that, they made the flashlight smaller, which was probably worth it. It's great as an EDC flashlight where you want something that can just fit in your pocket with your keys and not be too cumbersome. It works great with a NiMH AAA battery.

It is very small and pretty light.
