I updated my posting at http://www.impulsecorp.com/strike-it-rich-with-bitcoin-cloud-mining with revised stats for the 3 cloud mining services that I reviewed. All 3 are doing just as well after 7 days as after 5 days, and CloudHashers is still paying out after a week even though when I bought it it seemed to indicate it would only pay out for 24 hours.  On the other hand it will take around 8 weeks to break even, so I have no idea if it will keep mining for that long. I will keep the results updated on my original blog posting.
