Review: Real UV light, great for ID and currency verification - I'm a cashier at a Dollar General and I recently discovered I had accepted 2 $20 bills. They had no security strip nor watermark. I got these UV pens to help me identify the fluorescing security strip and to back-light the watermark. I've submitted a video which highlights these features. Very satisfied with these little UV penlights.
Review: Fun for kiddos - Took em camping and the kiddos had a blast looking at stuff at night

### ⭐⭐⭐⭐ Fun for kiddos
*by P***T on September 20, 2024*

Took em camping and the kiddos had a blast looking at stuff at night

### ⭐⭐⭐ False advertising
*by A***R on November 5, 2022*

It clearly states in the description that these light are rechargable. NOPE no batteries at all. I bought these as gifts for my operators. I was so excited as we use UV lights daily, and purchasing will not spend the money so all my people can have their own. I was pumped that we would be able to recharge them and I was pleased with the deal this offered. NOPE you have to supply batteries and there is no charge port or anything to indicate rechargable batteries can even be used (they can't as the case design is too slim to accept the "slight" increased diameter of a rechargable. THe lights themselves are pretty decent and they do zoom to a degree. I'm keeping them to give out as gift still, but now I have to drop another $15 dollars on batteries (I have 15 people in my line). so 2 stars for a decent light, -3 stars for the false advertising. Update. THey did take the rechargable battery out of the description, but I heard nothing from the company regarding my claims. THe lights do work for my needs so I moved them up to 3 stars
