My everydaycarry is a Fenix AA, about 10 years old.

Uses today included: checking on the henhouse, and going out back to smoke a joint, and I stuck it in my mouth to hang the hummingbird feeder. Before dark, I used it to help me vacuum in a hurry before guests arrive (lay it on the floor to highlight everything needing a cleanup), to look into a corner of the car trunk, to poke around in the storage room briefly, and at work to better look into the guts of a computer.

My swiss army knife got used a few times today, too. Different blades and tools. I’m semi-rural so dont leave the bedroom without those two items.

The thing about a small knife and a little flashlight is that you don't actually think about how many times it would be nice to have one of those things "right there right now" until you start carrying them. But a cheap little $15 flashlight that can clip onto your pocket and give it a try for a couple weeks, and you'll start to notice how convenient it can be every time you want to check something in a darker area. It's faster, brighter, and smaller than the light on your phone. This "WARSUN T7PRO Pocket Flashlight" is only $10 on amazon. It's not the greatest but you'll get the idea of always having instant light.

I just keep mine clipped inside the outer edge of my back pocket and the only time I ever notice it is when in sitting in a car. The length has never bugged me. I'm not sure how long it will last before dying aside from what they advertise it as. I've never had it run out on me, but I usually always charge it when it gets to like half.

Olight is a Chinese company, but they have real warranty\sales offices in other places. There's one in the US, for instance. Which is nice, because their arklights have a lifetime warranty, and that includes the battery. Obviously, the battery will eventually go bad and need to be replaced.
