Well it is fast. And the people are nice. The test itself however is inaccurate. I have never used anything in my life which few people can say, yet i tested positive. Of course they wont tell the company what it was I tested positive for. Just a sheet that says positive/negative. Maybe they just decided to flip a coin. False positives happen between 10-30% of the time so its necessary to be careful with the result and to be detailed.
