I never met a Geneticist who couldn’t immediately recognize this company as a scam. The product wasn’t the papers they send you after doing random marker tests once (so, false positives exist, and they never cared). The product is the DNA they collected by convincing people that their test was even remotely useful or insightful.

Its entirely based on correlation; and correlation to what? Geographic area? That makes no sense if you know one of any number of fields and many don’t even have to be scientific in nature, or genetics.

I have always hated them, always told people to never use them and get themselves a proper 50x full genome sequencing since it costed the same; and actually provides real, resolute and reliable data. Not just like borderline pseudoscience. Might as well sent in the shape of your skull.
