Client D


"Was extremely dubious when my wife suggested me taking a lie detector as I have only ever seen it on TV and did not think it was suitable. After speaking to Paul in the support team he explained the process and thankfully for the sake of our marriage I passed the test the following week. The examiner Dave reassured me that if I am telling the truth the truth will prevail and I can now see that this testing system can help a lot of people in similar circumstances"

Client E


"Thanks to Mike Rumble for helping us out with a Lie Test. My husband had been accusing me of false things for the past 10 years and I had enough so called them and they helped us to sort it out. We have agreed not to bring it up again as I have a report as evidence. Great work guys!"

Client F


"I had spent a lot of money on private investigators and previously on marriage counselling but could not get out of my head the thoughts that my wife was cheating on me. I had found messages also and did not trust her anymore. We came here as a last resort and although she did not pass the test and what I suspected was true... We both agreed to start fresh with honesty and see where we go."
