Just to update my SERP stats after first 3 weeks...
Ordered wiki 200+ package on 12.09. ,received my links on 13.09. - Speed 5/5
Content was more than decent, relevant,anchors and links are placed properly - Content 5/5
Communication was great too - Communication 5/5
Price - I payed discounted price and I'm very happy - Price 5/5

Now about SERP...
Used 1 URL and 3 keywords, progress for my main keyword is: 27 -> 16
I am talking about 201,000 exact monthly searches and moderate/high competition. Before this service I was stuck on page 3/4 about 8 months and think to give up of further investment in this project. Joe returns my hope in this... I didn't do any additional blasts or else after receiving these links. And, there is only 3 weeks after wiki links started with improving my serp, I am expecting more progress from this.
