I received a free review copy from the OP. 5 links + 5 extra, which is nice. The work was completed in a good time frame. All links (no follow) were on relevant websites to my niche and hosted on the Blogspot platform. All of them are using their own domains. OBL was low for most. Comments left were not too bad for this type of service. Readable and mostly relevant. Some of the sites are quite nice in terms of design, and seem to be fairly active. I would expect quite a few of these comments to stick. Because looking at some of the dates from the first comments that were left with links in the descriptions, they date back as far as 2013 and have not been removed. This service needs some do follow links added to the mix. But overall, a good service for tier diversity.
