Got my review copy...
Everything looks really good! All 5 are legit PR2s (big surprise right) and the sites look nice, are exactly as described etc. Links are dropped in the text and make sense, meaning it's not just your link with your requested anchor text dropped somewhere in the middle of a random paragraph. I've debated whether or not this is important, and I've concluded that even if it's not important now it may be in the future as THE ALL SEEING GOOGLE EYE becomes more keen with semantics.
The provided articles aren't exactly 5 star quality, but I mean $160 for 30 articles + getting your link on 30 domains... can't really complain, especially since the quality isn't important as long as they're unique and not unreadable spun CRAP.
All in all I'd give it a 5/5 for what it is. Yeah the PR could be higher, OBL could be lower, articles could be better etc... but I don't see those as reasons to berate the service. It's a cheap way to get 30 permanent links to your site that will probably get stronger over time. Get ittttttttt
