You must be a lot younger than I am. Out of all of the ones you have listed, the only one I am involved with is One Opinion, which is my best paying site, and I have only made $54 in two months, and I haven't gotten any products to test in probably two years either. I am also involved in my survey, valued opinion, mindfield, you gov and one other one which is not very active. I am also involved in Pi-Opinion, but I am never eligible for any survey with them, and I think I have $5 in my account now. I have done a few market research projects so far this year though. I did two in April, and then I did two in January. They often turn you down though if they find out that you just did a study. I just had one a few weeks ago that I am sure was a mock jury that paid $200, but when I told them that I did a mock jury at least five years ago, they suddenly were not interested in me.
