Works well

Does the job

Product worked as described, very satisfied.

The money checker is excellent

I bought this 2-pack for the register at my shop, hoping it would catch fake bills before they made it into the cash drawer. It took less than a week to pay for itself.​A customer tried to pay for a $4 item with a crisp $50 bill that felt a little too thick, almost like construction paper. I pulled out this marker and swiped the corner. The line turned pitch-black in about half a second.​When I looked up, the customer immediately said, "Oh wow, my uncle gave me that for my birthday, I had no idea!" grabbed the bill out of my hand, and practically jogged out to their car.​Pros:​Works instantly—bright yellow on real currency, dark black on standard paper.​Gives you quick confidence behind the counter without causing a huge scene.​Comes in a 2-pack so you always have a backup.​Cons:​You'll realize just how many people try their luck with terrible fake cash.​5/5, highly recommend for any small business.

WORKS VERY WELL.

I know feel better about writing a check now.

Lo use en una hoja de maquina y marco negro.Luego lo use en un billete de dolar en tres puntos distintos y en todos dio un tono diferente.En lo personal, no me ayuda mucho

Fonctionne bien

After getting a fake 20 here in Canada we opted to get this to check USD this has saved us over $60 so far. Well worth the money

It works perfectly and on all kind of money. Fast shipping and will again.

Perfect
