UV LED Flashlight Black Light UV Lights 9 LED Ultraviolet Blacklight Flashlights Pets Urine and Stains Detector on Clothes Carpet Rugs (8 Pack)

Having one of these is a must if you frequent any establishment where you could be sitting or laying where someone else was and you want to make sure they didn't leave anything nasty. If you frequent massage parlors or if you travel you need one of these to check for stuff left by the people that were there before you. It comes in handy to check yourself when you get home so you don't get busted. I also use it to make sure my facilities are clean.

I didn’t order enough with the first order, so here goes. Students loved them for our Glow Day Party!

I bought these for glow disc golf and they work great! I gave a bunch away to friends to use. Such a cheap good deal.

Very handy, I carried one with me in my purse to check things out wherever I sit or touch. Also have one in travel bag when going to stay at a hotel or somewhere new to me. Have to be careful.

Perfect for what I needed them for

I used these for fingerprinting for my forensic science class. They loved them

I bought these for my cashiers at a grocery store to check large bills, and they do the job for $20s and $50s but the UV light does not make the security strip in $100s glow and it's very hard to see any difference at all unless you really know what you're looking for. I have another UV light that does show the security strips on $100s brightly, which is why I was disappointed by these lights. Most of my cashiers are highschool student so I wanted a tool that would be extremely easy for them to use and see the security strip. Bummer.

Not extremely bright but perfect for what I needed.
