I have been using for a few weeks. It is a little querky and needs some manual intervention. I mainly use it when I am working for large agencies who's clients equate "detailed analysis" with page count. It generates a lot of data very quickly which paid for itself with the first "quantity" report I did.
The other feature I like the best is the matrix that it produces on the last page of the Top 10 Analyzer -- where your site stacks up against the top 10 for that phrase.
If you are looking for just the data then I suggest using one of the better web-based keyword density analyzers.
