I used it, and I think it's a pit on the whole. In fact, it's not just Elsevier's polishing pit, but their magazine is also a pit. I'm stuck anyway. There may have been no big grammatical problems in the paper (because they haven't changed much since they revised it for me), and then let me go to Elsevier to polish it. Once I felt cheated. I retouched the picture for the second time in advance, searched many advertisements of retouching companies on the Internet, and read everyone's comments on the Woodworm Forum. Finally, Editsprings was used to retouch the picture, and no language problems were received.
