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.

We used LetPub’s English language editing service, our paper was revised three times, and each time was very professional and detailed. We contacted the Client Communications Specialist by email throughout the whole process, they answered our doubts patiently, and the processing speed was very fast. Many thanks for LetPub's professional and meticulous service, and it is very helpful for future paper writing.

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.

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!
