Black Light UV Light Flashlight, 21 LED 395nm Ultraviolet Blacklight Flashlight Mini Pet Urine Detector for Dog/Cat, Dry Stains, Resin Curing, Matching with Pet Odor Eliminator(Batteries are Included)

Bright, small compact fits into your coat or coverall pocket. I got it to make finding chicken eggs much more easier! Light weight. Nice.

Great little light. Works well on uranium glass or to cure your nails where you need uv light. I've used them for both and it works fabulous. 10/10 would recommend

I bought this to help isolate areas where my recently incontinent elderly retriever was leaving urine, so that I clean as small an area as possible with a carpet machine or a hard floor machine. UV light like this causes uric acid crystals to fluoresce. The crystals are very small, but numerous in saturated areas. Using the light for the first time, I am reassured that cleaning removes most or all of the urine. The effectiveness depends a lot on the surface being examined. I have new carpet, marketed as pet resistant, with a speckled pattern to hide dirt. The speckled pattern also makes visualizing the crystals hard. It is much easier to see dried urine on the wood laminate floor and thus to clean only the places in need. The color of the surface is less important than the consistency of that color. The glow of the crystals is apparent on any homogeneous background. It makes me feel cruel, but I have confined both dogs (one without incontinence) to the hard floor areas of my house because it is not only harder to see the urine on carpet, it is also much harder to clean. The moisture imparted to the carpet causes the smell to persist for 24 to 72 hours even when the urine is mostly removed. Anyway, this light is partially effective in delineating areas in need of cleaning and thus reducing the need to clean the whole room, and for that reason helpful.

Works as advertised.

Works great for body fluids finding

Batteries died quickly. We used it to do a yard check for scorpions before we would take the dogs out at night. When the batteries are new it works great, but dter about 2 months of using it daily for a max of 5 min a day it didn't work as well

If you have cats, then you know that are masters at making messes. This little light does great at showing how poorly these little furballs are at aiming into the litter box. Not only that but it also can show the former location of hair balls once they've dried up. Admit it, how many times have you been in bed at 1:00 am and heard that unmistakable sound, only to not be able to locate it in the morning? I do like the compact size of this flashlight, so finding a place to keep it is not difficult at all. I just have to remember where I put it and hope my wife doesn't find it to use to check my aim.

Perfect
