I ordered a package of 250 and got my report in roughly 2 days. What others have said have been true - comments aren't terrible, but aren't great either, but either way they're sticking, so I could care less. In the majority of cases, there *will* be high OBL links, but out of the ones I spot-checked, a good number were those in which all the comments were on one page instead of your comment being bumped back to an older page.
The thing that did impress me, though, was that given this is advertised as "PR2+", I was expecting mainly PR2s with a few higher ones in there thrown in. However, in my 250 package, the fewest I got was PR2. I got a number of PR3s, and mostly PR4-PR5s. Was impressed by that fact.
Will be using again.
