I ordered 8 hours of market research on a topic from a user called ******** (incidentally, who now seems to have dissapeared).
I needed the research done within 24 hours. The reason for this was that I needed some data to put behind a presentation, to be done the next day.
8 hours intensive research on a specific topic was agreed, a price set and a deadline agreed.
The research was of awful quality. I could produce similar quality work in about 5 minutes. I would be unsurprised to find a young child with a limited grasp of English had done the work. It was so awful I can only assume the gig was taken in bad faith.
The research was delivered just after I had delivered the presentation, hours beyond the deadline.
I would never use fiverr for anything remotely serious again. I would advise everyone I meet that fiverr is a waste of time and money. Convince me otherwise.
