Good instructions are important. Check. Easy to use. Check. Now I know where to clean, and that I'm not as bad at housekeeping as I thought.

Very impressed with build quality and heft. Bought to use with UV resins for fly tying, and this unit matches the recommended specs for Solarez resins. I am using it right now for Loon Thin and it's working great at half the price of the best Loon UV flashlight.

Awesome light. It is shocking when you use a black light like this one to see how clean you think you’re getting things, like I said shocked . I originally purchased it so that I could properly clean where my old dog had accidents. Well this light makes it very easy to find where my dog urinated. It also shows every bit of I guess biologic, matter that was on my kitchen cupboards that was not visible to the naked eye. I also think if you hire people to clean this light will truly show how well they did. Just an FYI for those who have the linoleum and hardwood floors it’s very difficult to see anything on those surfaces. Any fabric ,Carpet, and cabinet it works great ,beyond what I expected.

I’ve looked at many UV lights and without a doubt this is the best light I found.

I use this when I clean the litterbox. Now I know the box and area around it are clean. I save a lot of time because I'm not over cleaning fearing I've missed something.

A great light for seeing pet stains. Do not order if you do not want to know how dirty thing are in you bath rooms and floors. Well made and worth the higher cost over cheaper lights.

Bought this to figure out where my older cat was peeing. Worked perfectly for that. Also helped me realize I need to do a much better job when cleaning my bathroom. Anyone living with men or men wanting to do a better job cleaning their bathroom, this is perfect for you, but be warned!! You may be permanently traumatized. Men, you may think you have the best aim in the world. You started out young. Maybe your parents put fruit loops or cheerios in the toilet for you to practice your aim with and you became a regular urinary sharp shooter. This light will destroy all those years of self confidence and show you how much splash there really is. Ladies living with men, you may start to make them sit down every time they have to number one. Or just use this light to figure out where your cat is peeing in your house like me and be amazed at how many things in your house light up under black light. Probably works really damn well at all the other things it mentions in the descriptions as well, I'm just scared to try this thing in a hotel.

I loved this. We have children in our home who are potty training. They don’t exactly aim correctly. This has helped us clean all the missed spots we thought were clean. We tried and returned a different light and purchased this one. It works great! Makes me feel more confident in cleaning.

Criminals who build fake Gibson guitars (most faked guitar on the planet) do not have the skills or time to do inlay on the headstock. They use a realistic looking decal that shows up under a black light. Works every time. This is a great tool if you work in a music store and buy used guitars - people will try to sell you fakes. This light can save you A LOT of money.

We have three dogs and a cat, and even though everyone is (theoretically) potty trained, we rarely get through a week without some kind of mess. Often, it's hard to track down the source of a suspicious odor, and I originally started looking for a black light flashlight to help with those searches. After reading the reviews for some of the most popular and least expensive black lights on Amazon, my impression was that many were underpowered. I wanted to be able to shine a light into a room and cover ground efficiently, not crawl around on the floor with a tiny flashlight that could only illuminate a few square inches at a time. That's the main reason I opted for the KOBRA. Although we don't plan to use the KOBRA outside the house, I like the fact that it's ruggedly built. Having grown up in an era when people used flashlights all the time (before flashlights were built into our cellphones!) I know the difference between a cheap flimsy flashlight and one that's built to last, and I'm glad I paid a few extra dollars for the latter.
