Here's what a former F.B.I. agent had to say about CheckMate

I have had the opportunity to use your product on three different occasions . Not withstanding the obvious  reason for the product, it serves as an additional tool for the investigator on behalf of the client to determine if sexual intercourse actually occurred. After being in the business for 20 years it is my personal opinion that most clients involved in these type of investigations are looking for positive proof before they make a decision about someone they are involved with. Surveillance Photos, written reports and audio transcripts all are helpful investigative tools.
