In general, I like this service a lot but there is a number of issues. There are duplicate days in 2019, 2021, 2022, and 2023 that aren't trading days, so it makes it difficult to line up with Google Finance (which is what the extension is modeled after). There is also data that is wrong for 2008, 2009, and 2010 and has to be manually corrected.Overall they have been responsive to correct errors in the past, but these errors persist. If the data was more reliable, it would be 5 stars from me
