Overall, it is definitely worth the price it's being sold for and with that extra discount, it becomes a bargain!
REVIEW
I was offered a review copy of the service and here are my thoughts(which would have been the exact same even if I paid the full price for it).
QUALITY
Twenty linked packed in an excel file were delivered as a link to my inbox. The stats of the links were as promised, all of them were above 15 DA and some of them were even in the range of high twenties so that was good. The RD was way above 30 too where some of them went as high as 80-90. All the links were active at the time of delivery and are now too(around a week post-delivery).
It's too early to comment on the rankings but they have been started jumping around so I'll wait for them to settle down before I say anything but there was some movement so that looks like a good sign. It was an overall great service, it's just that like all PBNs, the domains didn't have an SSL so the links were HTTP rather than https but again it's $1 per link so you can't complain much, I have bought way more expensive HTTP links before.
PRICE
A dollar a link? This beats Fiverr at its own game, minus all the taxes and bullshit. For that price, I am sure you cannot go wrong.
COMMUNICATION
The seller was active and all my queries were answered almost instantly via PMs and I'm sure it would be the same way for everyone else too, he seems like a great guy.
DELIVERY
The report was delivered within 48 hours while the TAT says 5-10 days so that came in like a surprise. The earlier, the better though as you get more time to get the links indexed and work on them further if you want to. The report was delivered as a Mediafire link in xls format which I had to download and go through the links. A quick suggestion to OP - for the lazy folks around here, try using one drive so the report can be accessed with one link directly in the browser, everything else was great!
Good luck with the sales.
