I have been using the UltraFire® KE3 for 30 days now, and it is absolutely phenomenal! It is incredible how such a small, lightweight keychain flashlight can produce such a powerful and bright beam. The aluminum build feels very solid, and the battery life is outstanding for its size. A truly amazing everyday carry (EDC) item – highly recommended!

The KE3 is a little marvel but it came on in my pocket the first time I put it with my keys. The switch should have a secondary lock or way to prevent it from turning on accidently. Metal shell and tiny led display is nice. Dual color lux modes is great idea, but it should include low lumen mode like moonlight 10 lumens for even better battery life. For such a tiny keychain light it is bright and rechargeable. Versatile and tiny enough to fit in the small pocket of your jeans. The tiny size is just that tiny to lose it so u need it on a lanyard or something to hang it from. Next upgrade should include double tap on switch and Ultrafire Lanyard to hang around neck or wrist. Good value and best little light around. Good job Ultrafire!
Dear Customer,
Thank you very much for your thoughtful review and valuable suggestions.
We sincerely apologize for the accidental activation issue. Your feedback about adding a lock function, a moonlight mode, and a lanyard is greatly appreciated, and we will share it with our product team for future improvements.
We’re delighted to hear that you like the KE3’s compact size, brightness, dual-color modes, and overall value.
Thank you again for your support and encouragement.
Best regards,

Attached some pics of the warm vs. cool light. Honestly didn't expect a keychain light to put out this much light. Perfect for digging through my desk drawers at night without turning on the overhead lights and waking everyone up. The little battery percentage screen is an awesome touch. Very solid build.

I’m a total flashlight junkie, and I usually carry lights that cost way more than this. But the KE3 honestly just kicked my expensive light out of my pocket. First off: thank god for USB-C. I'm so done with carrying weird, custom charging cables—I just use my phone charger and I'm good. It’s barely bigger than an AirPod case, but the amount of light this thing throws is insane. It easily beats out lights three times its bulk. My new favorite piece of gear, hands down.

Finally, a keychain light that isn't cheap plastic junk. I bought this specifically for taking my dog out at 11 PM. The little battery screen is a lifesaver—I actually know I have 40% juice left before heading out, so I don't get stranded in the dark. The bright white light easily lights up the whole sidewalk, and the warm setting is great for finding my keys without blinding myself. Solid metal, too. Never taking it off my keys.
