UV Mini 01D Blacklight Flashlight 365nm Keychain lamp, Suitable for pet Urine Stains, Stains, Minerals, Fluorescent Agent Detection, and Currency Art Identification, etc

Cheap. Light did not last long before the battery gave out. Not worth the money I spent. Poor quality. Definitely not for everyday use.

This light is so tiny and barely has a bright enough black light in it. It's the size of a nickel. I will be returning it because it to dim and small for what I need it for. Nice part was it came with 18 extra batteries.

UPDATE: seller reached out to me without me contacting them and refunded my money. So based on all things I change my rating to 5 stars. Would not recommend for use on key ring. The flashlight turns on and off by twisting the 2 pieces of the flashlight. I bought it to put on my key ring. The 2 pieces of the flash light worked itself apart from putting my keys in and out of my pocket and the bottom piece of light was lost. It only took 3 days for this to happen. If you turn the bottom portion tight and snug the light remains on and lasts only about 3 mins before it goes dim. So the bottom of the light is only twisted about 2/3rds up. It id why I believe my light twisted off so quickly. Would have lasted longer if it had an on and off button. So I would not recommend at all.

If I wanted to be picky I could probably rate it four stars because it's a lot smaller and weaker than it seems in the images. And I don't like that it doesn't have a button to turn it on it's one of those things where you have to just turn the battery casing all the way which makes me worry that it's eventually going to just fall off my keychain But oh my God this thing came with so many batteries lmao, it came with like 21 batteries and it only needs 3, and it was packaged incredibly and does work

This is so freaking cute. My girlfriend literally geeked out when I gave her this and then I remember that I gave a Virgo a flashlight that can see stains and she went to the bathroom. Turn the light off and check to see if I was cleaning the toilet properly. So thank you for giving her the ability to check to make sure if the bathroom is clean. And it matches her keys perfectly. I got the silver regular flashlight version and mine. Got scratched up and hers hasn't gotten scratched up (With the pink black light version) and that's fantastic.
