Small and fits right in the glove box, works great for it's purpose and was a decent price.

Holy cow this is my favorite new adult fidget toy. It has more weight than a pen and the soft click button to turn the flashlight on and off is very, very satisfying. I work in a place that uses UV lighting and UV reactive décor. This light is so handy for testing out colors in my art and 3D materials. The flashlight is best for the personal range but can reach across a room. If all the lights are turned off and in an enclosed space, the flashlight can illuminate objects at least 20' away. The packaging warns that this flashlight cannot detect cat urine. I disagree. My cat's urine shows up under the blacklight (see review pic). So does the egg residue on my unwashed frying pan (also in review pic). Soap and biological matter typically shows up under average range blacklight frequency and I'm thrilled to see this blacklight picks up on all the color ranges I'd like to see. The only issue is that my cellphone camera doesn't see violet very well at all. So the pictures turn out very blue while the human eye would show more violet. That's not the fault of the blacklight though.

Great product. I bought the flashlights or work. After buying them I keep one at home for cleaning motivation because I found my cleaning was not as I though with trying out the flashlight on my flooring. It detects dog messes and fine dirt partials amazingly and at work my co workers try to use mine instead of the flashlight provided that has taken its wear and tear from falling on the concrete and when needed you have to find it. That is why I bought my own and it works much better. Everyone is asking where I bought it on course I say amazon and give them the brand gearlight and it only takes 2 AAA batteries which is even better if a plus and I can put it in my pocket with my pen knife cutter and other tools. Work wonderful and would buy again and probably will. Seems very durable and should be taken care of as most tools and flashlight. Very happy.
