Great job and faster service than agreed. PRS was reachable via mail, but not via phone. Service recommended.

Very fast service and an adjusted price. I hope to review the next article again.

The reviewers of our article requested an English review to verify the errors. With the service of PRS we did not have more problems.

Performance has a large variance. I have used the service three times. For the previous two, the quality was great. However, I had a bad experience this time as I found quite a number of typos and errors in my draft after proofreading. The most disappointing part is that, when I complain, there is no response.

Excellent and timely review

I have used proofreading service twice, but the last time the editor did not completely correct the words, references and tables, which made me very sad about the work. I hope that such nuances not happen again. Thank's

The proof-reading service was detailed and helped us to generate a quality product that correctly communicates the message we wanted to convey to the readers. Besides, the time spent on the revision was short.

Everything worked fine.

I would like to thank you for the excellent work done quickly

quick respons within deadline text was markedly improved reasonable price

Swift and competent service. I would definitely recommend PRS to colleagues and others

thank you very good help. some times reviewers of papers made some critical comments of the English, but I think this is not always a problem of you. best Francisco

Contrary to my previous experiences with PRS, I was quite dissatisfied with the last proofreading provided. Even though many mistakes and enhancements were highlighted, most of them remained unchecked. After using a proof-reading service I would expect the paper to have no grammatical or spelling errors. However, I found many problems, both in terms of grammar and spelling. I ended up correcting the paper myself and using Grammarly.

It was very professional. Thanks.

This is our second appeal to the firm. As always, work is at its best. Very attentive attitude of the proofreader.

By using PRS, I have been able to publish more papers. The corrections were made by an expert in the field, *Excellent service*

We have never had any issues with the english quality of our manuscripts since we started using PRS services. =)

Professional and reliable. Thank you.

Hi. I had some problems with the editors, one of them told me that my work needed a professional edition, and that was after you send me the new document

Quick process. Good comments/suggestions.
