Anyone who's done these DNA Tests like Ancestry, Herritage, 23&me etc... How Accurately Do You Think These Are and Are you disappointed in what you found or pleased?

I was adopted, and very reluctant because I know for fact the chances of what I'm looking for is very slim to none, and don't need more disappointment if I don't need to, already traveled once to find it, basically came to dead end in person... Just curious of what people in general think, that have invested in these stuff. Comment below for further details of experience, thanks.
