I didn't expect a $30 keychain tool to be this useful - but I'm seriously impressed
"Talk is cheap, so I grabbed a K3 and put it to the test. There's a lot to the K3. It's an 800-lumen LED for illumination, which is quite an output for a small aluminum flashlight that fits into the palm of your hand. This light is perfect for dark nights and is far more powerful than the light on my iPhone."
"The UV light is perfect for spotting counterfeit currency, making glow-in-the-dark paint glow, activating UV adhesive, and detecting leaks . The UV light is a super useful feature once you learn how to use it. There's also a laser pointer, for pointing at things that your finger can't reach, or for anyone who gives presentations. Also: Are Ridge Wallets worth the hype?"
The K3 delivers 800 lumens from a small aluminum body that fits in the palm of the hand, outperforming typical phone lights for dark-night use. The unit includes a UV light useful for spotting counterfeit currency, making glow-in-the-dark paint glow, activating UV adhesive, and detecting leaks. A laser pointer provides remote pointing for presentations or hard-to-reach targets. A side-mounted multi-color RGB LED supplies creative illumination for parties or photo shoots. A hidden bottom lighter can start cigarettes, campfires, or log burners. A 750mAh USB-C rechargeable battery powers the many features, with runtime varying by use.
