I did try this again, and didn't see any results from it again on a penalised site.
I think it's probably worthwhile for a service which states in the title that it is medicine for penalised sites to have some balanced reviews, which to be fair are available in the OP. But negative reviews are needed for something with such a bold claim in the title.
For $35 you can't really complain, but i don't think it's any more medicine for penalised sites as any of his other $35 services are.
Some of these sites might just be recovering due to the recent panda update too. It's sometimes impossible to gauge what are the results of a service, and what would have happened anyway - especially with supposed penalties and recovery from these.
This would be great if it was fine tuned slightly and advertised simply as a social media service.
