I discovered Edanz through the BMC recommendation. I had previously used another language editing service, but soon discovered how much better Edanz is. They are fast, thorough and give me so many useful tips. The best thing about Edanz is that they not only edit my language, they also comment on the scientific quality. Valuable and extremely helpful advice. Even my statistician was impressed with the knowledge the person editing my manuscript had about statistics. I have no doubt in my mind that Edanz has helped me increase my chances of being accepted for publication. I have recommended Edanz to all my colleagues.
I just want to add that I am very thankful for your excellent work!
