This is awesome to say the least. Multi function and rechargeable. The regular pen light and a cib panel that is very bright both led and a 365nm uv light for finding pet stains and many other organics. Like stained or unclean bed sheets at a hotel. We all know what that means and who wants to sleep in loved up sheets? YUCK!! Being rechargeable is great too because no dead batteries or replacing them. Just plug into a 5v phone charger with the provided USB type "c" cable. All this wrapped up into one nice package can't be beat. I almost forgot about the magnet in the adjustable rotating pocket clip. This would be great in many ways including for yourself or as a gift.
