This is the second time I've polished my paper, and I have been recommending my classmates in the laboratory to edit their papers with LetPub. The effect of the revision is quite good, and the revision is very comprehensive and careful. After submission, the reviewer did not raise any questions about the language of the paper. LetPub's account manager is also very enthusiastic and responsible. They patiently communicate, and answer any questions, provide good service, and even send emails during the holidays.

I am very grateful to LetPub for its editing of papers, professional language modification and timely feedback of papers. I look forward to cooperating with LetPub again in the future.

I have cooperated with LetPub for the fourth time. LetPub is very professional in clinical article translation. The article submission went very smooth and has been accepted. I will always choose LetPub!

Thank you to LetPub for the professional revision of the manuscript. The polishing effect is exceptional. The language problems pointed out by the editors and reviewers were solved easily.

The English editor (scientific editor) not only polished the English of our manuscript, including grammar, punctuation, and overall readability, but also significantly contributed to the academic expression by providing constructive feedback on the paper's framework, constituent elements, results, and conclusions. This included appropriately compressing lengthy or repetitive sections, suggesting structural modifications, identifying ambiguous passages, rewriting academic descriptions, questioning certain statements in the paper, and offering constructive academic suggestions. All of these insights and assistance have been very inspiring and helpful for us as authors. Thank you very much to the editor.

I have used LetPub for language editing of SCI papers three times. LetPub's paper language editing service is very professional, the revisions are very detailed, and the revised manuscripts are returned in a timely manner. At present, LetPub has become a must for Ph.D. SCI submissions in our research group.

Thank you LetPub very much for polishing my article. The journal accepted it for publishing right after language revision. Before the journal editors referred me to LetPub, I had given my manuscript to another language editor, but it did not go through. I am grateful for LetPub's professional and detailed approach. LetPub's service is highly professional and totally worth the price.

Thank you to the professional editing service of LetPub editors. After the editing, the wording and grammar level of the article has been greatly improved, and the article was accepted smoothly.
