I got my article.
Before writing the article, the author contacted me several times - to clarify the details of the order. In what style the article should be written, the target audience, and some other details. The article is well written. It is noticeable that the writer was studying the topic of the article. Of course, it is only 500 words. A detailed review of the article's subject requires much more text. I checked the text by complex settings of uniqueness - the article is 100% unique.
I am satisfied with the work done.
