I decided to use this service after receiving a free critique from a job website. The critique seemed well thought out and reasonable. Once I purchased the service, I didn't receive a response for several days, but finally was notified my revision was underway. First draft seemed professional and crisp, but none of the suggestions offered in my critique were referenced nor discussed until I brought them to the writer. This seems strange to me. However, my final version included and answered all my comments and provided some description on why decisions were made. Overall I am pleased with the result, though I am still in process of using new version in my job search.
