Ancestry DNA has far exceeded my expectations. I am thrilled with my results and trying to be patient waiting for the raw data and a search function. I think this is due to several reasons:

About half my ancestors arrived prior to 1750 and those are the vast majority of the matches I have found. I have no matches to my 25% Swedish lines who arrived in the 1850s.

I have a generally well documented tree solid for 5 generations with many lines going back 10 or more generations. This has helped greatly with matches.

I spent literally hours studying genetic genealogy and antosomal DNA testing. I knew what to expect and what not to expect. And I am spending hours sorting out all the results.

If you think these tests will create a family tree without work from you, you will be disappointed. If you mostly copied other people's undocumented trees, you will be probably be disappointed because you are looking at too many of the wrong ancestors.

Ancestry has clearly had a better than expected response. They are scrambling to keep up. Be patient, and I hope your results will be as helpful as mine have been.
