Review on 🔦 KunHe Black Light Mini Flashlight Small and Lantern Combo: USB Rechargeable UV Flashlights 395 nm – Ideal for Detecting Dog Urine, Pet Stains, and Bed Bugs (Pack of 2) by Richard Counts

For me, this is the best keychain flashlight and I've had about a dozen different models. This one does everything. It's a great size and easily fits my keychain without adding extra weight. A quick press of the button puts the beam on high mode and it's very bright for its size. A double press takes you into manual mode, where you can cycle through the different brightness settings. Three clicks turn on the side LEDs, which are very bright and perfect for camping, room lighting, etc. This mode alternates between low and high white lights, red lights, and flashing emergency red lights. You can get one that replaces UV with red light. And it glows a little after being used for some reason I don't understand. Battery life is excellent and it charges externally via micro USB. That's a damn good flashlight. I have no negative feedback. Easy 5 stars.
