Working with the LetPub team was one of the easiest and successful collaborations we tried so far. They have made a professional job regarding the graphical abstract and exactly fulfilled the vision what we had about the figure. The communication and flexibility were outstanding; it was a pleasure to work with them. Altogether, the work reflects high professionality and excellence, and the service is highly recommended.

The whole service process is very smooth. Designers can understand our ideas very well, and the drawings are relatively fast. The final journal cover was also successfully accepted, thank you!

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.

LetPub is very good and very professional. The manuscript was returned on time and the manager Zhu is also very nice. After the article was polished, it was successfully accepted.

I am very satisfied with the polishing service provided by LetPub. Due to the strict deadline, I asked for a quick turnaround. The staff was very patient and very active in helping me. I would like to express my heartfelt thanks to the LetPub staff!

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.

LetPub’s editing service is very good. We had our work edited with them several times and every revision is very helpful. Our Client Manager Meng, who provided great customer service, is also very patient and meticulous. It is indeed worth recommending!

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