My review:
I got 10 high PR comments as a review copy.
Here is the page PR breakout, including the 30% bonus comments:
PR2 - 5
PR3 - 7
PR4 - 3
PR5 - 3
I checked with scrapebox the external OBL and I got between 24 and 140. Internal links were higher.
Each page had from 7-8 comments and up to a few dozens.
DA 30-65
PA 1-30
OP perfectly used the anchors I sent. Only 2 links weren't live, but it's ok since he made 3 comments as bonus.
Comment example:
"A core part of one of the fields is mostly done by many people who are experts in their field. Usually there will be a lot of very important changes that should take precedence."
1 main thing that I would improve is the usernames used to leave the comments. There are pages where OP used the same username for the comments. This is quite a footprint.. and if someone wants to find your list is pretty easy.
The quality offered is usual for this type of service and for the cheap prices OP is offering.
Good luck with your sales OP.
