Hmmm I ended up giving up on the essay... though I had 2 other essays that completed to my satisfaction.. now I know there is a bit of luck involved in getting a good writer..
you must be joking! I've got a couple of versions of the essay I asked them to write, and what I got was RUBBISH! with plenty of mistakes that foreigners usually make. What they offer is SCAM, not good work...
I think I can make make sense out of that:
It's always the case that there's luck involved, simply because the quality of the work depends on which writer happens to take the order and even the worst companies might have a few good writers. The problem is some companies apparently don't limit themselves to hiring only qualified writers but take unqualified writers and ESLs who can't write well enough in English to write for native English speakers. Their best writers might give you a good paper, but there's just an unacceptable degree of difference between their best and their worst and they (apparently) don't care or can't afford to reject writers who could never get hired by companies that do care and can afford to hire only qualified writers. Personally, I couldn't imagine paying good money for a paper and then hoping that I get lucky every time I needed an essay.
Always pay by credit card and say something very specific in your order (like "I will not accept any work written by an ESL or that misuse any basic English vocabulary or idiomatic expressions and I will dispute the charge if this essential element of our contract is not met"). Then, if they send you any ESL garbage like that essay, at least you know your credit card company will back you up 100% and the essay company might even make the effort to refer your order to someone who can actually write in English in the first place. Also, use this forum and Google extensively first and don't ignore very negative reviews that sound credible just because there are other reviews that are positive.
