I placed an order to test out this service, here are my thoughts:
Price:
Certainly cheap as advertised, cost should not be an issue to anyone.
Service/Communication:
wfjose was always VERY easy to contact and replied quickly to all PMs. The work was turned around in about a day. There are a minor mistake on one set of links (anchor text was spun but I didn't want it spun), I notified him via PM and he fixed it within an hours (plus gave me a second discounted package).
Value:
This service is exactly as advertised: cheap blog posts. I intentionally gave him some lower competition long tail keywords, it'll obviously take a couple weeks to see the results but I expect it'll help. If you have a highly competitive keyword I doubt it will help unless you "juice up" the link.
Content:
The content posted on the blog was decent enough, not looking to get traffic though, just wanted contextual links
Overall, if you have a page/site with mid to long tail keywords I would recommend adding this to your toolbox. I would recommend you bookmark (maybe even Drip Feed Blast) the posts to give them extra juice.
