Recently received the report and I am very happy with the quality of this service overall.
All of the websites that my link has been posted on either have PR3 or PR4. The DA of all root domains is 30+ and PA is good too. TF could be better (one domain has the TF of 1). The websites don't seem to be a part of a PBN at first glance and are run on different CMS with different designs. All the domains have different WHOIS information too.
The quality of articles is good. I appreciate that they took the time to manually write articles on a topic that is not very popular and there wasn't a lot of information available on it. I have noticed some grammatical mistakes, but the content is easily readable. Relevant images have been inserted into each post.
The SERP of my new website has gone from N/A to #25, so the results speak for themselves.
