Well, I got the essay. It was written by a native English speaker and the grammar and vocabularily were fine, but it wasn't anywhere near 2:1 standard. Narrative not analysis in the main, tho' I had said narrative was not required, and it rambled away from the point.
However, I used it as a base to build on. Probably used about a third of it, and had to put in about 5 hours work myself. So - expensive for what I got. It was the first time I've used an essay writing service and I won't use one again.
