Review :
I received 2 links as a review copy from OP.
Stated metrics :
TF 19 RD 38 CF 26
Checked metrics : RD 76 (ahrefs) TF 11 CF 16 (root domain).
Please note I don't know the methodology OP used for his metrics so it may differ from what I did, explaining the different metrics. Overall, it's still in the stated range or even better (RD) so this is NOT a problem
Many of the backlinks are blogspot blogs. Regarding the blog post itself : blog uses a simple design. Nothing fancy but well, does the job. Contact and privacy pages. What I appreciated is the OBL, as the time I'm writing this review there is only 4 blog posts in there, so I hope it will stay that way and won't become another 100+ OBL PBN.
Content is not money-site quality of course, but it is well readable and you can clearly see there was some research involved as I gave OP a very narrow niche. One relevant image was added.
Stated metrics :
TF 24 RD 24 CF 32
Checked metrics : RD 14 (ahrefs) TF 16 CF 19 (root domain) .

Backlinks from local directories.
Blog theme is nicer than above. Sharing buttons included, overall more realistic. Regarding the content, same notes as above apply (low OBL, good content, relevant picture etc..)
Overall : Great service you have there. OP does quite a good job at building PBN. Nothing exceptional (which is completely understandable looking at the price tag) but far above the average PBN on BHW (oh dear god). One thing that could be improved is the quality of the domains. I only saw 2 of them but well, it does not seem so powerful at my eyes. But hey, we all know metrics sells more than results or good backlinks so it won't affect your sales anyhow ...

But again, this is a side note and this is already a good service as is. Wishing you good luck for your sales !
