Alex was kind enough to offer me a discounted review copy and I ordered 7 homepage links from him. Here's my short review of the service.
Delivery
Alex managed to complete the order in 24 hours which is extremely fast by any standard and especially when compared to a number of sellers on this forum. The time it takes for a seller to deliver an order is important to me, and I find it extremely annoying when a seller not only misses the deadline, but also fails to inform you, leaving you to waste time chasing them up. I cannot remember the last time when I purchased a forum service of any kind that was completed in 24 hours, so this is a big thumbs up straight away.
Websites
I asked for a list of websites related to my niche and picked a number which I liked. Since I had already seen the websites I wanted, there were no surprises about what I received. The metrics of the websites are solid:
PR-4; 10 years old; Page Authority - 44
PR-3; 17 years old; Page Authority - 47
PR-3; 5 years old; Page Authority - 39
PR-2; 15 years old; Page Authority - 46
PR-3; 7 years old; Page Authority - 41
PR-3; 14 years old; Page Authority - 45
PR-2; 17 years old; Page Authority - 36
All the websites look completely legit and do not look like your typical public blog network in anyway. If you've ever bought posts on a blog network, you'll know that they all look pretty much the same no matter who you buy from (spammy looking, crappy wordpress theme, all articles with 1 keyword rich link and easily identifiable on first glance as being part of a blog network) but these websites look extremely natural.
Links
The anchor links were placed nicely to blend in with the original content of the home pages. My concern would be that the more links which appear on these websites the higher the chances of them looking like part of a network. I hope that Alex puts a sensible limit on the number of outbound links on each homepage.
My advice to potential customers to help preserve the integrity of the network is to think carefully about the keywords you are going use so that they appear more natural to fit in with the website. For most of my links, I deliberately did not choose my main keywords as I figured they would look a little spammy in the context of the website. Instead, I chose related LSI style keywords to try and suit the existing theme to help them blend in. I can only hope that other customers may think to do the same.
At the end of the day, the most important thing is the effects that these links have on your own website. It doesn't matter if the links were delivered late or the website looks like shit, as long as they have a positive impact on your target site, that's all that really matters. Since these links were only placed literally an hour ago, I cannot comment on their impact as yet, but I wanted to leave this review as I promised Alex I would do so. I will update my rankings in a few weeks.
