This man is not at all professional. Meets at his house which is a disaster. It appears the machine he is using is from the 1960's and he kept apologizing and starting over because it wouldn't work. May have come out of a dumpster. His results were not accurate at all. He didn't even have a computer nor ability to email a result. He has some neighbor type on an old school typewriter the results then sends them US Postal. Waste of time and money. Wouldn't even take a payment to his Company. Had to be Cash or check to him personally. Should have walked out right there. Be warned.
