This light works TOO WELL. I got it in order to find out where else my cat may have peed and not only did I find out, I found probably 200 years of god knows what. I live in a 200 year old converted house and there are things on my walls that are probably older than I am. It also works crazy well for finding lint, as it turns out. I bet you didn't know that even if your painted walls look uniform in color...they aren't. Or that you could find out whether tobacco smokers have smoked in a place using a black light. I got a second hand couch and it looks clean, but I'm sure you can guess what I found. Dont' get me started on my visually spotless toilet and sink :( One of my sheets had splotches on it despite being clean and having no odour so I guess if there's some invisible damage or change made to your fabric items, you'll be able to see it with a blacklight.Anyway, it works really well. It's bright, or whatever you call it. Stuff shows up extremely well. It has a nice weight to it and doesn't feel cheap. The packaging was straight to the point and included a charging cable and a wrist strap (so that you don't accidentally throw it at somebody when you gesture in shock at what you find, surely).It worked out of the box but I'm charging it up now so I can traumatize myself some more and check my work after a Deep Deep Cleaning this weekend.I guess that could be a potential downside. You might night want to touch anything in your home ever again if you look at it with a blacklight.

I bought this to identify ringworm on my foster cats and this works so well. It is very strong and can also be used for looking for any cat urine on surfaces. I like that it is rechargeable and think the materials are high quality.

This black light flashlight works perfectly, is well made and delivers an extra bonus by being rechargeable via USB port. It's the best buy in terms of price and value.

It comes with a manual with basic but useful info, a short but decent USB-A to USB-C cable, and a small lanyard. I got it to cure UV solder mask that I used for a PS5 repair, and it worked pretty fast. I've also found it useful for revealing stuff that may be hard to see in normal conditions, like dust and grease. It's pretty fun to use in general too. It can get a bit warm if you leave it on continuously or use it repeatedly in a short period of time, but not to a concerning or uncomfortable level.For $11, it looks, feels, and works very well, and it seems like it's more than good enough for whatever I might need a UV light for.

Works great for detecting stains in hotel rooms!

If you are looking for an inexpensive uv light to use for Mini Brands, this worked well for the Hello Kitty sets . It also was kinda “fun” to walk around the house and look at the walls and bathrooms in the dark. Don’t say I didn’t warn you, lol.

it works perfectly. our cat started psraying randomly for the first time 2 weeks ago and we have been using this thing to check every nook and cranny. the crissis has passed now but this thing saved our lives! we were able to see every spot that was affected and i was able to see the urine spots melt away when i sprayed them with enzymatic cleaner. amazing! i was considering getting the $40 UV light that was being advertised here on amazon but this little $10 one works amazingly! why would i spend 4x the price. also, fyi, stone tile can be fluorescent, as well as dust and food stains are also fluorescent. use it at night for ease of use. it also works in the day, you just have to have the lights off and be a little closer to the stain. i think the optimal distance to see the most definition of urine is probably 10" away. but it works from a few feet to scan the area before getting up close to clean the stain. good luck fellow cat owners!

I bought this black light specifically because it is advertised as having 365nm UV light instead of the more common 395nm. From everything I've read, for cat urine specifically, you need a blacklight in the 365 nm to 385 nm range in order for it to show. I already had a 395nm blacklight, so I bought this one specially to help me quickly find spots left from my kitty, who has crystals and sometimes goes outside the box. This unfortunately DOES NOT WORK FOR CAT URINE. I am so disappointed. It works amazingly for anything else, the bathrooms were lit up, and I was very grossed out by that. I know for sure it doesn't work for cat pee, though, as there were two specific spots where my cat went, and neither showed at all with the blacklight.
