Portek Rechargeable Mini Keychain LED Flashlight with 365nm UV Blacklight, EDC 60lm Bright Spotlight for Night Walking, Black Light as Cat Dog Pet Urine Detector Scorpion Detection (Gray)

This small, key-sized light which is easily carried on a keychain has made checking bills easier than ever at work. I constantly come across potentially suspicious bills and this verified authenticity with ease. Especially with the issue of counterfeit pens constantly getting lost or ruined by fellow coworkers (by ruin, I mean pressing hard, using to draw, etc.). Those $50 and $100 bills are easy to verify in front of managers (as per manager check requirement). Performs as advertised, though I don't like how the buttons are configured (x2 press for UV, long press for flash). Device stays cool during and after use (even after prolonged use). The 2-hour life of the battery is quite long lasting as you normally wouldn't need it for that long in a single sitting. Charges quickly (provided you're using the provided cable or similar fast-charge capable cord and plug). Many of my managers and coworkers are interested in getting one now after seeing mine perform so well and it's ease of use

Pretty nifty light,As far as the UV light goes, it does great, the main draw back for me is how short the life span is on the actual light portion.But I bought this primarily for its rechargeable compact uv light.So overall 4/5 stars.

I received my order & there wasn't a flashlight in it. I returned, but was 1 day late, so I never received refund. But another one, but the battery lasted 3 weeks. I'm out over $30 for the two of them.

Really nice keychain light. Small. Easy to push buttons, and very bright. I love the black light feature

First unit that I received was not working even after charging all night, and the replacement one is working, but UV seems very weak, still testing
