COSOOS2 UV Black Light Flashlight, 2 Pack 395nm Mini Pen Light with Clip, Waterproof Ultraviolet Flashlight for Leak, Pet Urine, Scorpion, Hotel Inspection, Dry Stain and Bed Bug.

Do not buy these and go roaming through your kids bedrooms like I did! You will most definetly be disgusted! The light is bright and it is designed to be as big as a normal pen light. It fits perfectly in a side pocket of my cargo pants that I constantly wear for work and half the time I forget that im even carrying it. The battery life last for atleast a month and a half of course depending on usage, and I use mine ALOT. i have dropped it, thrown it, kicked it stepped on it and its even been ran over buy my truck and it still works without an issue. I'd say its designed really well and quite versatile to say the least. I would recommend but again.... dont use it on your kids bedrooms!!!

I was skeptical at first. Thought why not. Getting ready for a big trip. Might as well see what I’m sleeping in. Lightning is very bright, it’s more of a spot beam. Have been gone for three months and though it doesn’t stay on long still shines bright. Metal construction holds up well, small so it’s easy to pack. Check out some pics. Not it’s not a giant beam but for quick, easy and lite couldn’t ask for more.Stayed at numerous hotels so far. Didn’t see anything and was beginning to think it was a gimmick. Checked into a hotel today. Boy was I wrong. This light works.

These little things do wonders. They are both amazing and evil at the same time. They find every spot you missed. As far as the battery life goes I would invest in some rechargeable batteries from Walmart or wherever you choose to get them from. Your battery life depends on the brand you get. They will save you money in the long run. This flash light fits perfectly in your pocket and takes up as much space as a sharpee. As far as the design goes it holds up against accidental drops. Overall it’s a good flashlight, and a decent investment. You find yourself using it a lot more often then you realize.

These are extremely useful for all kinds of things. My only problem is that they don't have rechargeable batteries.

Thermy are nice and cute ones. Each of them needs 2 AAA bateries. They have small power, but at night, switching off your lights, then you can see well color differently with the black light. It is nice to have in your pocket or near you to you time to time.

Bought this portable Black light for traveling.you can check how clean your room really is from any stains on the sheets ,bed cover floor ,especially the bathroom….i changed room once because there were stains on the bed sheets and looked as if they didn’t change the sheets on the other bed …….,then you can see how clean the bathroom really is ,another time I checked the bathroom mirror and it was all loaded with small specks which looked like people flossed in front of the mirror you couldn’t see it until you turned off the light to check ,,had front desk send someone up to clean the mirror ,usually I try to do this upon checking in .just close the curtain using the black out curtain also so room is dark you’ll be amazed what you see…

They’re very useful for finding out things and making glow in the dark things glow

Just as advertised. Good quality metal casing and strong light beam.
