Just got my review article and I had a better experience than Angelo above.
The article was delivered quickly (took me longer to reply with my topic/keywords).
qualo was able to squeeze in all the keywords I was looking for into a relatively short article while still maintaining a professional flow and reading experience.
His English is great - obviously a native speaker. No grammatical or spelling issues aside from one missing apostrophe. All sentence were coherent and well constructed.
I'll be giving him another, paid order, tonight.
