I ordered a package D on a very competitive 3rd page keyword for a site which has first page rank for 100s of relatively competitive keywords. The service does seem to have coincided with a small change in keyword placement - so it will pay for itself, just from that. My real goal for the service isn't to rank for that particular keyword; rather, it's to increase my overall authority on the keyword so that less general keyword combinations will get a boost from the target page. I'm confident this will help.
The articles appear to be spun. Some are closer to natural english than others. There are sentences and headings that don't make alot of sense. The report also provided the login information so I am currently tightening it up. I am happy with the service overall and would consider using it again.
