I've had this model torch for 6 months, and it's been great. USB C rechargeable, and simple to operate. It's got 2 modes, moonlight and full chat. All the other Keychain lights I've found have annoyances for me… Like strobe modes and buttons that get pushed too easily in a pocket. This is simple, twist a bit for low, and a bit more for high. Undo it, and the USB port will become exposed for charging, but the head will remain attached.
I doubt this'll get too popular, there are loads of alternatives out there, but this is a quality little unit that's very bright if you need it to be. OLIGHT did have a deal where you could get it for "free", with 8 buck postage, but it looks like you already had to have spent a few bucks previously in their store to qualify. That offers not currently on, but according to comments, will probably be on for Christmas.
Blue and black are currently cheap, orange (what I've got) is an extra 3 bucks or so.
Honestly a worthy addition to your Keychain.
Great keychain light, compact, bright, intuitive to use, and the low mode is nice and easy on the eyes if you just want a little light.
You'll qualify for this light on your second purchase with olight, that includes buying another "free pay shipping" deal. So first $8 shipping you'd get the AAA version, second deal (and thereafter) you'd get the usbC rechargeable for $8, as long as they're on offer
