Have ordered and received two packages - just ordered the 3rd. One site didn't show much improvement, but I honestly wasn't expecting much. The domain isn't an EMD, it's already got some age and a number of backlinks built to it, and competition is pretty tough.
However, on the other site, it bumped be from bottom of 2nd page up to mid-page 1, settling in at the bottom of page 1. Also saw all inner pages of the site improve in rank (some very drastically) for their own specific KWs, as well, which I'm assuming is due to the juice flowing through from the TLD to the inner pages.
Package I just ordered is for a site that made page 1 in 10 days, and ended up settling in around 7 or 8. Built a number of backlinks using posterous and Link Juicer (have since quit). Posted an article to UAW and got 130 or so submissions. Pinged all UAW submissions and saw the site shoot up to #2 for about 2 weeks. Dropped to #3 for a few days, and since back down to #6-8, depending on the day. Am interested to see what this package can do for this site!
