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

"thank you very good help."

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.

"Contrary to my previous experiences…"

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.

"All of good"

It was very professional. Thanks.

"Oligonucleotides-transformers for nanoengineerin"

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

"By using PRS"

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

"They are great"

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