Well... so far I have ordered 9 articles. I thought it was for 9 original, but I guess it's sort of a combination of both. The keywords were all closely related, so I can see how that would be an issue.
Out of those 9 I would say 6 were great off the bat.
One just had some slight inaccuracies about the product, but not a big deal especially as this is for adsense & probably won't be thoroughly read anyway.
One article largely described another related product (like describing the benefits of leather shoes when it is supposed to be about cotton shoes) That's not the actual subject, just an example.
And one article was for a long tail keyword & the last word was left off, which actually made it a completely different product.
I have asked for re-writes of the last 2, as they were completely describing different products than the original keywords requested. It has been about 8 days since I first requested rewrites by email, 4 days since I actually made contact & requested rewrites by IM. I believe he said they were having internet issues, so that may be a factor. Anyway, will report back after I get those.
Overall, I would say the ones that were done right, they were done very well, & I will be ordering more articles, but not for anything that I need done quickly.
