I just received the report for my first order of this service. The report is very detailed and I received a lot of extras, such as nearly double the number of article submissions advertised. I spot checked some of the URLs and everything seems to be there.
I can't comment on any effects on ranking yet. I've been seeing massive (positive) ranking changes on most keywords I'm targeting for this site in the last few days. That includes the single keyword I targeted with this service, but since I'm seeing increases across the board (i.e., for keywords not targeted with this service), it's hard to say how much impact this service had on the ranking. I'll try to remember to update this thread in a week or two if anything changes.
