I had done a couple of papers on here. So far each paper came out good and I had no issues with it. I would still run it through a plagiarism just to double check.
However, An advice I would give is do not put the actual due date. Make it at least 5 days before the due date of a paper. That way if they turn it in late to you for (any reason) you don't lose points for it in your school (or wherever you need it).
I had this happen to me for one of my paper but luckly I put it 1 week in advance so I didn't turn it in late.
