My review is going to be different and here's why:
Before this was an official service (before this thread) a couple of months ago (I think) Matt came to me and did one of his little "Quick, I want you to test something for me" Which means I have to throw him a site without really thinking about it before I loose him to his ADD.

So I looked around for a site that I didn't have too much vested in (just incase anything went wrong with one of Matt's little experiments)
So now for this site background:
I purchased domain (aged) and built site back in April. Local niche. Managed to get to number 1-6 on about 10 terms for a few months. And then around August, I think, my site started dancing. I mean like it was freakin bi polor or something #2 one day 2 days later it would be #450 then next week #1 then a few days later # 430. Yeah yeah I know about the dance. But a) I wasn't doing anything special to cause this (no sudden linkbuilding) and B) this went on for
3 months. I've never heard of that sort of google dancing going on that long. I still, to this day, don't know what caused it. I have some theories, one maybe around that local filter rumor out there (this is a competitive niche for local) So at the time Matt came to me I had pretty much given up on this domain and was in a "yeah whatever fuck it" mood.
Ok here where the review gets really really foggy. I forgot about what Matt was doing, forgot to update stuff and I think Matt forgot I was testing it.
(By now Matt and Jason are reading this probably going "Fuck this is the last time we ever get Turbz to review ANYTHING")
So long story short (too late) I am now back at 1-6 for 18 out of 24 keywords. Been sitting there for about a week (that I know of, could have been there longer but since I forgot to pull the daily stats...who knows). Not sure If I'm going to start dancing again but for now it's steady.
BUT WAIT THERES MORE!
The other part of the story is I had no backlinks showing up. NONE after all the link building i had been doing and drippy feeds and backlink gurus and magical genie carpet ride link building, NOTHING. (No dis to those other services as I still religiously use them and they def have their place in keeping me a SERP Queen of my own domain) Suddenly with Matt and Jasons services my backlinks Shot up from 2 to 500 to 1200 to 2000 and now at 3030. When I first saw that I choked on my diet cherry pepsi, thinking well crap, my sites never going to stop dancing. But nope, apparently this is indeed what it actually needed.
So the moral of my long and ridiculously random story is:
If you want Good strong stickable backlinks AND SERP pop, then you want to give this service a try.
Disclaimer: Due to my terrible reporting and tracking and with me starting all of this testing before it was an actual service, I haven't been able to get the full effect of the service, reports and what not. I will most likely be using this again soon and hope to come back with a much more organized review.
