I received a free article in exchange for my review.
The article is well-formatted and very readable.
I think the quality of the article is decent for the price.
The writer knew to spend more time on the beginning paragraph, and the rest is pretty typical for a 'best of' type of article.
It only required a little editing.
A report was included with the article, showing no real signs of any plagiarism.
Overall, it seems like a good service.
