Counterfeit Money Detector Pen

Pros: The price is cheap. It detects USD without any issues.

Cons: Can't see any thing wrong with it.

Other: I bought this because every so often I sell stuff to people in a face to face environment. When handed cash, I'm always worry that it's going to be a counterfeit currency and I'm going to be ripped off. Now with this pen I can check the cash given to me for a cheap price.

Pros: Works on any kind of paper money - (the pen is built with material that reacts with wood-based paper to create a black stain) Money that is made from fiber based paper (all the paper money that exists) doesn't get any chain reaction or paints it with yellow. The pen it self has a very low price in the market here it costs X3 more so i'm very glad (i bought 3 of these)

Cons: Absolutely no cons the product is perfect!

Other: The product is worth they money spent,it has a wonderful built quality and it is very easy to use.

Pros: - Detects BRL without any problem.
- You can carry it everywhere since it's like a normal pen.
- It's cheap. I'd never find anything like that at this price in Brazil.

Cons: No cons at all. It works as it should and the price is ridiculously low.
Actually, I think it smells kinda odd, but I don't know why since I don't know what it's made of.

Other: You can also give it as a gift.

Pros: It detects counterfeit currency
Small, in a convenient pen size package

Cons: None that I can see.

Other: I would buy it again. I would still do the standard checking of the watermarks, etc to determine if the currency is genuine, but definitely the pen will help weed out bad currency.
