They have even offered me up to € 3.50 for a survey. Sure, this one said it took about 45 minutes and I decided to do it. Over time the questions became more and more specific and if you did not meet the criteria, which happened to me, they ended up closing the survey telling you that it was not for you. In other words, they had me answering probing questions for the survey for about 20 minutes and after one or two questions that they probably didn't like, they took you out of it most of the time. I don't think there are such well paid surveys or you have to be an alien to answer them.
