Guarantee

All our work is guaranteed and includes a certificate. Please note that reviewers' judgment of English is very unreliable. Many reviewers are not native speakers of English, and unfortunately these reviewers often criticize English that is grammatically correct and well written. We hope that our certificate at the end of your document will help to prevent this problem. Please note that the guarantee does not apply if the text has been changed after Textcheck and before submission to a journal. We therefore recommend that you ask us to approve any changes made after Textcheck.
