Working with LetPub for a journal cover design has been a wonderful experience. The artwork designers perfectly understood the main ideas and requirements for the cover with scientific accuracy and aesthetic vision. The customer support staff was very helpful throughout all the process and provided timely updates about the progress of the project. I do recommend this service and surely will use it again in the future."

The first time I cooperated with LetPub, the feedback was very professional, and some of my conceptual errors were corrected. I would recommend it to colleagues and friends in need

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.

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.

The article was polished only once and accepted to publish. LetPub is very professional and the language polish is excellent! Thank you very much!

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.

Thank you to LetPub's editing service for helping me, who has just passed the 4th level of English, and published a Q1 paper. The successful publication of this paper would not have been possible without the editing services provided by LetPub. In addition, the polishing experts also put forward three insightful opinions on the content of the article, which is enough to prove the professional level and professional competence of the polishing experts. I hope I can write more articles and have more cooperation with LetPub in the future.
