Review on 🔦 RENOOK 21 LEDs Mini UV Black Light Flashlight - 395nm Detector for Dog Pet Urine Stains, Bed Bugs, and Scorpions - Authenticate Currency, Fluorescent Agent Detection - Mother's Must-Have Camping Tool - 2 Pack by Angie Strongheart

Both broke before I even used them. I didn't need them for a few months before I bought them, so I couldn't return them when I found out they didn't work. When they first came out I turned them on and they worked but after 2 months when I really needed them they felt disconnected. I pressed the button at the top and both of them were engulfed in the flashlight light. Obviously they only work if you press the button once, not the second time. waste of money.
