Review time...
My order was delivered today. I ordered a (small) silver package. I was intrigued to test the service and pointed it at a web 2.0 that's been aging for while, but has no other links to it.
You'll have to wait to find out whether the links work - I'll post a ranking update at some point in the next couple of months.
In terms of service,
@marrrko is a good guy to work with. He answered questions up front, including giving some sample sites. I'd recommend him as a seller.
The thing to bear in mind when ordering this service is that everything comes at a price point. These are low priced links. There are sellers on BHW offering blog comments and forum posts for more. The reason to buy is because it is good value. I doubt anyone will be able to compete for high competition keywords by using just a small package. More likely, you're going to be powering up T1 pages, boosting social media pages or ranking a particularly profitable parasite.
What impressed me most is that my requests for URLs and anchors were followed perfectly. They were placed in articles where they made sense, and where the article was relevant to the target site. I don't know how unique the text was because I haven't checked. But it is well written (given my experiences with other PBNs).
Another good thing was that I could use the 50 links with many different URLs and many different keywords.
The sites themselves look like general multi-niche sites. Obviously this isn't a niche specific PBN. That is probably the biggest downside - the next article in the list is selling a completely different product or service. But that shouldn't surprise you given the price. Quite a few designs are basic. All have unique logos.
So in summary, this service clearly isn't designed to give you the highest quality PBNs. Its giving you standard quality at incredibly good value.
I'm going to be really interested to see how my web 2.0 ranks.
