I received a free review copy with 50 profiles created.
The work was completed in a reasonable time and delivered in a professional report. There was an issue with the original delivery, the wrong description was added to the profile pages with my link. I alerted OP, and he advised it would be fixed. Within a few more days all of the profiles were updated and now had the correct description.
I checked almost all of the links, and almost all of them had a live direct link. Maybe 1-2 I could not locate a link, and maybe 1-2 had redirects instead of a direct link. The OP advertises that the anchors are naked URL, brand name and domain name, but all of the URLs had generic anchors like "click here" "click for info" and naked URLs. I don't think a single one had a brand or domain name for the anchor.
These are pretty generic profile links in my opinion. They look like spam backlinking, I would not be satisfied if I paid the full price, and I would ask for a refund. OP told me the links were manually done, but the quality is not any different from using a bot in my opinion. I have used bots for this kind of link building in the past and I was able to do more customizations than OP offered me.
Perhaps OP can offer spinning of descriptions or such for buyers, but I was only offered a short description and that same description was copy/pasted to all the profiles.
I haven't been deep into SEO for a while, but I have concerns about these profiles ever being indexed. OP can maybe address those concerns. If you can get the links indexed, my experience says that you can boost your domain authority and page authority with these links, but I am not up to date enough to say if they will help with ranking.
My recommendation is to take advantage of the free trial if you are interested in this service.
