Review:
Communication: While using the form I found there was no way to upload files since I wanted to supply them myself. Other than that minor inconvenience there really was no need to go back and forth.
Turnaround: It took longer than I hoped it would, and the OP did not provide any turnaround expectations so I was a little in the dark. I received the finished report within a few days, so no prob.
Quality: The spinning is not human readable, which was expected with the price. After looking at a random sampling of 25 submits. Out of these 25 sites, 3 were completely down, and one was throwing up a malware warning.
As for the blog comments, they are on very high OBL pages full of real spammy shit, though since this is basically a free add-on I'm not complaining.
Results: The SERP boost kicked right in over the next 2 days. My rankings are slowly receding and will eventually "stick", so I'm not sure what the final conclusion will be - but so far what I see is looking great.
Overall: I think OP has a damn valuable service here. Very happy!
