OK, I purchased a review copy of the services provided (10 PR4 and 5 PR5 blog comments). The blog comments were delivered as promised. I sampled all of the links and found that almost all of them stuck. One did not survive moderation, but he provided an extra comment as part of the package so I got what I paid for.
Communication was OK. He was a little slow in delivering the services and after I asked about it, he said he was having electricity problems, which were causing a delay. He followed up shortly thereafter with the completed work report.
seo-world, I'd also encourage you to delete the above comment where you call me out for not leaving a review. You only delivered this work completed at 1:10 pm on November 6. To leave a post less than 24 hours later saying I'm not being fair for not reviewing it is a little over the top. Bear in mind the following:
1. You were slow in delivering the work to me.
2. It's a weekend right now.
Communication issues notwithstanding, the work was done as promised and I'd probably hire seo-world again.
