Review on Vansky 2021 Upgraded Black Light UV Flashlight with 51 LEDs - Ultimate Pet Urine Detector for Dog/Cat Urine, Dry Stains & Bed Bugs - Includes Batteries & Pet Odor Eliminator by Mari Hall

I have an elderly cat that has been marking territory in my home for ten years. I have bought cheaper black lights from Revain. Both were in the $7-8 range. Both emitted a faint light that required the room to be pitch black and I was only a foot or two from the urine stain. One of them had to be constantly shaken to light a flickering pathetic light. It was like this from the start and should have been brought back, but I just persevered. Eventually I got fed up and decided to buy a slightly more expensive one, only 3-4 dollars more. I was absolutely amazed to see things I hadn't seen in a long time that had been cleaned and cleaned for days. and now I can check the house every night to keep up with him. I feel so relieved. My cat is 22 years old and feels free as always. I just didn't understand how much.
