Dri Mark Tri-Test UV Counterfeit Detection System, Black (351TRI)

This product is a piece of crap. Batteries do not fit - the connection is loose and will not provide light to verify whether it is counterfeit or not. I would not recommend buying this product.

This system takes a huge worry off your shoulders! With new ways to get around counterfeit pens, the tri-test gives you two extra detection methods for an even more accurate readings!

These are very cheaply made and they break easy, if they even work when you get them. I would just find something else that does the same thing.

This is a must when receiving money. If you've ever received counterfeit money, you will be glad you have this. It is easy to operate

Not the best quality but is half the price of the one that we purchased in the past and gets the job done. I would buy another one if needed.

The great thing about these detection systems is that they are portable so you don't have to worry about plugging it in. They're also convenient for checking I.D.s to prevent under age drinking.

The city i work in is a tough place. Was always getting fake bills that the markers couldnt detect. Once i got the balck light counterfeit light, we didn’t except one! I love this thing!

these are fantastic waste your time buying the cheaper one. this is the one you have to have. they free up space on the cash register.

We were having a problem with counterfeit money in our town and this was easy to use and if I had any doubts about a bill I didn’t except it and never got stuck with a counterfeit bill like others did in town.

One of the best tools to have to identify counterfeit money. The light allowes you to view the entire bill to make sure you aren't getting robbed

This is a great counterfeit detector for any establishment that accepts cash in this day and age. With the multiple sure proof methods this is a sure winner. It has saved us on a few occasions. It has already technically paid for itself.

I have been using the pen for a long time, until counterfeit money makers got smarter. This system not only has a pen on it to check the paper, but also a UV light that let you clearly identify the markers of a real bill.

This has been a helpful tool. It is great for detecting fake IDs also. The black light detecting correct colored security strips is most helpful feature for bills.

This device showed up in a beat up box, however it works great. To prevent fake bills in the restaurant. I would recommend this product.

After receiving a counterfeit $50 a neighboring business asked about out 3-in-1 Counterfeit Bill Detector that we've had for a couple years now. We purchased this for them -- an incredible price that is sure to save you in the long run.

We use this black light to eat us when we pick crabmeat. The blacklight helps the bones shining really bright makes it easy to pick out.

We use this nightly and its a very clean sharp looking machine, very light and fits easy with the decor. This is a great buy from WR.
