Men, do you suffer from the nightmare of suspicion and doubt caused by the infidelity of a cheating spouse? The CheckMate 5 Minute Infidelity Test Kit is scientifically formulated to actually monitor your spouse's sexual activity outside of the relationship by detecting semen stains that can be found in undergarments after sex, and it can give you the "instant information" you need to deal with an impossible situation.

The CheckMate 5 Minute Infidelity Test Kit^™ created the underwear testing revolution in 1999 and was the first product or service of its kind to be offered to consumers. Described by some as, "The ultimate men's product"  CheckMate is the non destructive home use semen detection test used on women's underwear to instantly uncover evidence of sexual activity outside of the relationship. Yes or no results are obtained immediately without staining, cutting, or damaging the article in any way.

A normal cleansing action of the female causes a condition we call flowback which can cause women to secrete small amounts of semen for up to 72 hours after unprotected sexual intercourse, resulting in dried stain in the underwear that can be instantly detected with CheckMate.
