I put in an order for 30 total links back on 8/17. The initial delivery was pretty quick, but was also incomplete - half the PR5s and one PR4 were missing from the report and 8 of the links on the report did not contain my links.
I was promised a completed package, waited... waited... finally a second theoretically completed package was delivered on 9/19.
Ordered: 10 PR5, 10 PR4, 10 PR3
Between a combination of the 2 reports, this is what I ended up with:
4 PR5 links
6 PR4 links
7 PR3 links
Was that worth $190 USD? No, I'm pretty sure it wasn't. I also received a free PR6 link, but it has since been removed. At least the links that have stuck have lasted a month, so I know they probably won't disappear like the rest.
Will I order again? Eh... maybe. Chances are I will stick to the lower PR links though, as they are more likely to stick over time.
Dofollow blog commenting is an extremely volatile service. I am not mad at the OP despite the lack of sticky links; at least he communicates well.
