I used it for my masters research project and paid approx £300 to get target audience. As they highly advertise of being quality and all but to my surprise I paid a huge amount for junk and gibberish. The users in reality wrote "nhdjdjd" kind of replies. I contacted customer service more than twice but they maintained that I didnt set the filters right. In short, they charge you for no service provided. I would advise everyone out there NEVER to waste money on survey monkey paid responses. I am sure their own staff sits down and fills them.
