I received a review copy in exchange for this review. The following review is unbiased:
Metrics:
The metrics of the blog were exactly as stated they would be in the OP. The blog had a clean history and had no spam anchors.
Content:
The content was readable with no glaring mistakes. However, it was rewritten entirely from the page that I had the blog link out to. That's not really something that I like to see when buying PBNs. At least it's relevant.
Blog Design:
The blog was using the default Wordpress Twenty Sixteen theme with no changes made to it. To me this is a big no-no. PBNs these days need to have changes made to the theme, logos, banner advertisements, subscriber options, social sharing options, etc.
OBL:
My post was the only one on the site. The Wordpress theme footer links were still on the site.
Overall:
Assuming you get the lower package at $7 per post, I think the service is good if you're only chasing after blog metrics. However, the lack of design on the site really bothered me and comes across as the seller being lazy. If the seller is lazy about taking 20 minutes to design a PBN site, then they may be lazy about covering up all footprints.
I wish the seller the very best of luck.
Edit. Seller reached out to me and is going to "I am sure within a 24 hours i will fix all my blog theme , logos, banner advertisements, subscriber options, social sharing options, etc.."
I will update review afterwards.
