CheckMate helps find proof of sexual activity for the detection of cheating, infidelity & more.

Checkmate detects semen on undergarments, bedding and other surfaces.

Utilizing similar technology used in rape and homicide investigations, CheckMate detects and uncovers the traces of fluids that can almost always be found on surfaces after sexual intercourse. And while CheckMate's technology was first invented for private investigators, law enforcement agencies and DNA labs, this product was designed for use by anyone. 

Each CheckMate test kit can test 5 to 10 items without staining or damaging the article in any way. CheckMate will also detect semen from men who have had a vasectomy, and bodily fluids such as female secretions and or blood will not interfere with the test.

CheckMate includes easy-to-follow instructions and a manufacturer's money back guarantee.

    Is my spouse cheating on me?

    This is the question that goes over and over inside my head. Thanks to CheckMate, I did catch her before making a fool of myself any longer. What she did almost destroyed me and left me with nothing. I'm thankful that I have recovered and proved myself better than my cheating spouse.

    Case closed!!!!!

    Checkmate is the real deal. I had some clothing tested at a certified DNA Lab that is ISO certified and have all the legal certifications a lab has to have. The same clothing I tested with Checkmate, the Lab found to be positive for sperm and semen. They even sent me micro pics of the little devils. All this was after I had the items checked with Checkmate. This product is the real deal, case closed!!!!!!

    It works

    So, this definitely works, and further cemented my suspicions, but the Insite kit has a lot more test strips for just a few dollars more. I guess Checkmate is good for short-term, and InSite for long-term?

    Caught a cheating spouse, just like the ad said

    Sometimes life gives you lemons, and this time, life gave me a quick divorce with indisputable evidence. On to greener pastures.
