I had mine done because I was curious about health traits and genetics. I used 23 And Me about 12 years ago and still log in every so often to see new health reports and fill out surveys. It's been very interesting! They identified a couple of genetic diseases I know I have and have been more right than not about other traits.
I gave my dad a subscription as a gift and yes Maury, he is the father. My ancestry turned out to be pretty much what I'd been told it was by my parents -- half Italian, quarter Finnish, quarter Welsh.
I'm not particularly interested in genealogy but have almost 3K genetic relatives in 23 And Me including two second cousins. No idea how big a database it is, but it was surprising to have so many matches. I get emails every so often from people trying to pin down their connection to me, but I know very little about my ancestry beyond my grandparents so am never any help.
There are privacy concerns of course, but I've had a lot of fun with it.
