My wife and I both did 23 and Me, with the health stuff too. Then she did Ancestry because it goes more in depth. The health stuff was neat, and was pretty much spot on. The back hair, balding, etc where all right for me as well as other stuff. Both tests for her were the same, just more in depth on one. I am exactly what I thought I was based on what I was told. My wife did not have any idea what specific country her family was from, so for her it was cool to see where her roots are from. Ancestry did go into more depth for her. And she is more Native American than Elizabeth Warren... which isn't hard I'll admit.
We did it last year when the same sales were going on, hard to beat the price.
