Review on 🔦 LE Black Light Flashlight - Small UV Lights 395nm - Portable Ultraviolet Light Detector for Invisible Ink Pens, Dog and Cat Pet Urine Stain - Includes AAA Batteries by Robby Fingaw

Works as advertised! Batteries are included so I was able to open the box and use it right away. Bought because I smelled pets in our basement den that we couldn't find. We turned off all the lights and scanned the floors for pet accidents, which we found several thanks to this light. They should be pretty close but I didn't press my nose to the ground or like someone here said they should - standing up I could shine my light around and see the pet's urine stains quite easily. It works best on carpet and the darker the better, but the carpet underneath is off-white and it worked great there too, as we did notice a few crash spots where we felt something. We were aware of a stain on the vinyl in our laundry room, but it's very light and shiny, so we either cleaned it well enough not to leave marks, or the surface was too shiny or too light to see. It also showed cracks in the walls that we wouldn't normally see and scuffs on the wooden floor that weren't visible with the lights on. We also learned a lot about all the stains in our kitchen that never seem to have been removed! Had a fun family adventure in the dark and would definitely recommend. For this price you can't go wrong. Much better quality than I expected. My teenage son asked if he could have his own because he made everything glow really cool. It's going to be a great stocking this December and if we need another one I'll be buying this again. My guess is that if it's used a lot the batteries will need to be replaced often like all our other regular LED lights like these - they're SUPER bright but will burn out the batteries (we try to use rechargeable ones).
