This pocket-sized flashlight has 51 LED lights to illuminate anything that needs extra inspecting. It works just like a regular flashlight, only when you shine it on something dirty, the object will glow. However, it doesn’t highlight any old dirt, it’s typically used to detect, ahem, bodily fluids. It’s popular for picking out puppy piddle and kitten tinkle, but people use it for a lot more than that.

Some pet owners got a lot more than they bargained for when they went in search of “accidents.”

“Works very well,” wrote a dog owner. “[I] can see all the places my dog got to in lurid detail.”

Another pet owner noted a plethora of new discoveries: “I bought this because I suspected a stray cat has been spraying the outside of my door and I wanted to ensure I cleaned it off completely. When I received this flashlight, I waited until dark and had a look. Come to find out my own cat was clearly spraying back! Then I proceeded to tour my house with the lights off. I. Was. HORRIFIED. I thought that stuff on CSI was supposed to be fake!! So now I’ll be cleaning every room in my house from the doorknobs down. Also- why the heck are my toenails glowing?!?!”

If you think you have a clean house now, Amazon shoppers say this black light will spark a cleaning frenzy to make it spotless.

“My house is a pigsty,” wrote a convinced customer. “This light is fantastic but it shows EVERYTHING. I thought my house was clean. Turn off the lights at night, shine this light and be prepared to be shocked. Tomorrow, I have a date with a bucket of ammonia and water.”

“This light let me see into the future,” another shocked shopper shared. “It also showed me that I'm a disgusting person. There are stains practically on every inch of my house.”

If you’re a germaphobe, this is a tool you don’t want to travel without. But if you’re not a germaphobe, the Vansky black light might turn you into one.

“BE VERY CAREFUL,” warned one shopper. “NEVER take this into a hotel room... just don't... please please don't.... it's everywhere... just... everywhere... what happened in here? How many films have been shot here... oh my goodness, it's on the tv... how'd they get it on the tv.... I'm just going to sleep in my car....”

"Compact enough to keep in my luggage," a savvy traveler shared. "Great for inspecting the motel rooms. You will be amazed and disgusted at the same time when you see it."

Another customer noted: “Body fluid can't hide from this sucker.”

Gems and stones

Not every use is geared toward gross discoveries. Some people use the light to spot gems.

“I use this black light for jewelry and vintage glassware,” a happy shopper shared. “Great for identifying pearls, rubies, fake plastic beads, bone beads, amber & other organic gems. Shines vintage uranium or manganese dishware (it's safe!) super bright green/orange and activates [a] glow in the dark stuff.”
