This is on my list, but still haven’t done it.
Some decades ago dh and I did the Oxford Ancestors one though - the one that was supposed to determine your remote ancestral maternal and paternal roots.
How accurate it was I don’t know, but v interesting anyway. Dh and I turned out to have the same male ‘father’, dating back some 20,000 years, but he was also ‘father’ to IIRC about a quarter of all native Europeans.
Our maternal ones were different. His was traced to SW France, and maybe 25,000 years, and shared by IIRC 20%, so a mere parvenu compared to mine ? NW Greece, 45,000 years and only 11%. Same as Cheddar Gorge man, funnily enough.
Results were presumably dependent on DNA found in bones in those locations then. I dare say genetics have progressed a good deal since.
I’d be interested to do the modern DNA test, at last partly because one dd has colouring unlike anyone else in the family - the sort of honey-olive Mediterranean type skin that tans so easily.
Since some of my GGparents were from both coastal Suffolk and coastal Devon, I suspect some washed-up Armada sailor somewhere!
