2 Pack UV Flashlight, 12 LED Handheld Blacklight Flashlight 395nm Mini Light Torch Detector for Dog Pet Urine Stains, Bed Bugs and Scorpions. (Batteries not Included)

It almost works too well!!! Just remember detergents will fluoresce under black light, so spots you previously hit with your carpet shampooer will glow too. VERY helpful in finding pet urine spots and great price!!!

The COSOOS 2 Pack UV Flashlight set is a great value and works exactly as expected. The 12 LED blacklight design is surprisingly bright and effective at revealing stains, pet spots, and other hidden marks that are hard to see with normal lighting. They feel lightweight but still durable enough for everyday use. The handheld size makes them easy to carry around the house or take on the go, and the simple on/off operation is very convenient. Battery life is solid, and having two flashlights in the pack is a big plus—perfect for keeping one at home and one in the car or garage. They’ve been reliable and consistent every time I’ve used them. Overall, this is a practical, affordable, and effective UV flashlight set

First, let me start out by saying the customer service is excellent. When I received these, one flashlight had some LEDs that didn't work so I was super bummed. Currently I have no transportation so getting around to return them would have been an issue. So I contacted the seller to see if there was any other way to fix the issue. Honestly, I was just hoping to be sent a package with postage paid so that I could send it back and have it replaced. The seller sent me a whole new one without issue and it works perfectly fine it! It was very quickly replaced and I'm super excited! Now for how it works. These are super bright to be so little and they work awesomely. I was able to see hard water spots on every surface it appeared and stains in my carpet that I wasn't even aware of. I was able to see spots that I had missed, cleaning around the toilet. It works perfectly. It even works better than and is much more lightweight than the more expensive one I was replacing it for! An added bonus is that because its a UV light, it makes my glow in the dark tv remote covers glow brighter and longer than they ever have. I have issues seeing things in the dark because they sort of blend in. So it's now easier to see them in the dark than it was before. In closing, I would definitely recommend these flashlights and if there is any issue it will be handled because like said, the customer service was excellent and there was no hassle what so ever. Another added bonus, you can't beat the price. I paid less for two of these than I did for my old one which was around $8 more and had less LEDs. So I'm definitely satisfied with my purchase!

Not super bright, for lower level uranium, it has to be super dark in the room to tell. Good for travel and thrifting though

Works GREAT to locate Tomato Hornworms at night on the garden tomato plants! The awful worms glow green under black light. This has saved my plants. Great product

They’re not very powerful. It did not work for what I bought them for but not totally useless. If you’re wanting to use this for rockhounding in the river, this is not the one to buy. But it works in the dark and that’s just fine.

Bought these because my cat had a phase of missing the litter box and I was going insane trying to figure out where the smell was coming from. First night I turned this off and did a sweep of the room and oh my god, the things this light reveals. Spots on the carpet I never would have found with the naked eye lit right up. Cleaned everything properly and the smell is finally gone, so mission accomplished. For eight bucks getting two of them feels almost too good. I keep one by the front door and threw the other in a drawer for backup. They're tiny, like smaller than I expected, easily pocket sized, but the build feels solid with the metal body instead of cheap plastic. The 12 LED version is nice and bright, definitely gets the job done in a dark room. Couple things worth knowing going in: batteries aren't included, so grab some AAAs before you sit down expecting to use it right away. That caught me off guard but it's a minor thing. Also you really do need the room pretty dark to see the stains clearly, which makes sense but just so you know. Beyond pet stuff I've messed around checking IDs and some currency, and my kids think it's the coolest thing ever for finding scorpions and random glowing stuff outside. Genuinely useful little gadget that punches way above its price. No complaints at all.

We had a cat who was spraying and sometimes finding where it was hard to find. We used the UV flashlights and showed us exactly where it was. The visibility was clear and evident. The flashlights are small and compact easy to store and hold. They were durable and the power of the light was strong.

Para su presión es lo mejor que hay sirven muy bien luz potente dé noche

Cheap uv flashlight for charging up glow-in-the-dark resins and fishing lures. Does the job.
