My review:
Comments were delivered extremely quickly (within 24 hours, although he probably would have done it quicker but I am from Aus so different time zones). Links looked like they were all there 99%+ and most of the fails were timeouts.
Targeted a whole bunch of difference phrases and inner pages and all the links and whatnot match up (correct anchor for correct link).
Moved up some places for nonprimary keywords (went from 8th to 1st for one), dropped one rank for my main keyword although google has been bouncing me around and I expect this to go back to normal/rise in a week or two. Not something I am worried about.
The only cons of this service is the amount of targets matt might have in his arsenal, I checked a few of the links manually and it looked like about another 10-15 comments had been posted after mine (I checked about 12 hours after I got my report). Obviously not all of these are matt, but if it continues at this pace then you're going to have pages with crazy amount of OBL and the links will become worthless.
That being said, I'll be ordering a few more packages and pointing them to less competitive phrases and see if I can dominate with them.
