Just received one 800-1000 word article (it was 991 or something).
Gramatically I'd say it's about 75%-80% decent. There's just some small gramatical errors that are easily fixed, it might appear to some people reading it that the author's native language is not english, but most won't notice.
Spelling and punctuation are both fantastic, it's mainly some of the wording that's slightly out.
As for content, the article was VERY WELL researched and my keyword was used appropriately throughout the article.
I am very pleased with the article so far, but it took a bit longer than expected, but still it wasn't too bad.
tldr; some slight gramatical issues, but nothing most people would notice. Service took/is taking, a bit longer than expected (but apparently there's a large amount of orders atm) and for the price I think this service is great and would definately recommend.
Oh only real negative complaint I have is the title for my article was incredibly stupid, but that's really easy to change
Thanks ankur, looking forward to receiving and reading my other articles soon
