I have a good experience using this certain service. The fact, is I am a non-English native speaker student studying abroad. Therefore, it is sometimes tempting for to deal with the amount of writing work I receive. Firstly, before I mastered (at least partly) my language skills, I had to work hard to finish my papers on time. Usually, they did not receive highest grades due to grammar issues. That is why I applied for this service to help me. It was not an easy choice, but I decided to try.
The result has fully satisfied my needs. They re-write the paper I submitted, without changing main claims and arguments, however, the writing style, grammar, and vocabulary transformed dramatically. In fact, it is a good way to edit own articles for people who do not feel confident in writing English. Certainly, 5 stars.
