Honest Review:
I received a 763-word article with no plagiarism.
While reading it, it seemed as if I had read it before. A quick Google search revealed that it was a Page 1 rewrite. Surprisingly, not only were the sentences just rewritten in the same order, but the writer even used the same headings in the same order. I decided to give the service the benefit of the doubt and brought up the issue with their support and they offered to rewrite.
5 days later, I received a new article and it was definitely worth the asking price. The writer had done his research beyond just collecting info from page 1 and had presented it in a manner that flowed really well. There was no fluff to fill the word count and no overexplaining of the facts.
I wouldn't fully blame OP for the first article that came back as a rewrite since when you deal with lots of writers, a bad one might slip one, but would have definitely blamed him, had he decided not to do something once informed. Since they immediately offered to rewrite without trying to contest my claim and came back with a top-notch article, it means that there is accountability and a customer won't be cheated.
However, I would still advise OP to better vet the writers and put them on notice that rewrite attempts will mean immediate removal since the price they charge is above average and even I would not have known about it, and the only reason I did was that I had done my research and was about to write it myself.
