ive ben using it for a few months and i agree its a great resource. be sure to diversify ur keyword lists and try not to get too many links directly to ur money site, especially if the domain isnt aged... my advice would to have a as many second teir sites to have the keyword variations filtered to ur home site. there is reporting and you can check ur links, some are bare and some are anchor but a nice variation. the best feature would be the sheduling. i generally load it up with a couple dozen urls and about 30 different kwds per run, at 500 links a day, but i tend to skip days between niches. sometimes i'll let it marrinate for a week or two between niches depending on the age of the domain. pretty clean backlinks, profile links, so there isnt really any other links on the page which is nice.
