Hi,
I will try to make a review as objective as possible about this service.
I purchased the gold service, and am definitely happy about it.
In the first report I received, some links (social bookmarks) were not the ones for my website, a guy of the team made a mistake (probably a copy paste mistake) while during the report.
I sent an email to Eduardo who answered in a few minutes (don't remember how many exactly but less than ten for sure). He apologized for the mistake and promised to fix the problem.
Less than 24 hours after, problem was fixed, with a lot of additional backlinks as a "compensation" due to their mistake. That was very kind from him and I think that other services should take them as a model.
The links seem fine (some of them are even really great spots I did not know about) and start giving some results but I think this is still a bit early to see all the results, but I am very optimistic about it.
Thanks for the good work, keep on this way !
Flo
