Feedback Comment: Cons: 1) Plagiarism was detected in the project delivered. 2) Sentence structure lacked quality, edition was needed. 3) Demanded payment as soon as the project was delivered, rather than giving the courtesy of time to receive the final results of the delivered project, however agreed to wait 5 days for results to return. Pros: 1) Always available. 2) Willing to write an abstract without being originally included. 3) Product satisfied the requirements. * Deserved Bonus for writing abstract, but in consideration of the plagiarism and the poor sentence structure, the bonus was forfeited. Had the services of expert4u before, will use them again, perhaps the service provider rushed through the project to complete other projects.
