I have done several but they pay so little that it's not worth it at all. They send TONS of surveys my way but you have to qualify for them and maybe you qualify for 1 out of every 10. In addition, sometimes they only take the first 10 or 20 respondents so you're excluded in that regard if you don't get to your email timely that day.

I have done a few of them and those were all legitimate. I think it takes more time than they say but you can earn a little bit of money if you have enough time ot spend a few hours a day on it....I have used inbox dollars and cash crate. both are great and easy to use.
