Many thanks to Doris, a client manager at LetPub, for helping to get our cover illustration production work started during the National Day holiday week. Despite the tight turnaround, the final design met all the requirements and was successfully chosen by the journal for the cover. I will choose LetPub's service again in the future. I wish LetPub great success!

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 editors of LetPub are very meticulous and professional. This is the second time I have chosen LetPub and I recommend it to my peers. I give a sincere praise, and I am ready for the third time.

Thank you so much, LetPub, for providing great services at a very affordable price. I am especially thankful for your efficiency and helpful advice to maximize my article publication chances, even in the most unusual circumstances. I definitely will come to you if I need similar editing services in the future.

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.

We had a smooth experience translating our design to beautiful Cover Art using the LetPub Cover Art service. The process was easy. We met with the team, filled out a form, and provided a conceptual drawing to the team. The team made an exceptional draft cover in one week. We requested a minor revision of the draft cover, then it was done. We will definitely use LetPub's cover service again!

The editor made grammatical changes to the article: such as the correct use of "a" and "the". In addition, the editor also modified the expression. After revision, the article is smooth and easy to understand.

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.
