Here's my review:
The Good: good price, decent turnaround time and he way overdelivered on the links which is great.
The Bad: there was a mixup on the report that took a few days to figure out (turns out he gave me the wrong report).
The Ugly: I randomly sampled ~10% of the links. Here are the results:
DoFollow: 64%
NoFollow: 24%
Bad URL: 6%
No comment on page: 6%
So, I'd give it a B-. Also, most of the PR's appear to be 0. Very spammy blogs which you'd expect, not sure how much authority Google's gonna give them. We'll see.
