I’ve had bad experiences with iPoll. I’ll answer the “screening” questions and am told I qualify to take the survey, then once the survey is around 90% complete, I’m told the survey is “closed”. My guess is this is how they’re getting their data without having to pay participants. I’ve also gotten “invalid website” in the middle of some of their surveys as well, of course, after answering 15 minutes of questions.
“I participated in an in-home product trial study. A coffee machine company sent me one of the coffee makers along with about 200 coffee pods. I received $7 for completing 3 short surveys. Plus, after the study, the company said I could keep the coffee maker. So, I got like 4 mos of coffee for everyone in my household, a free coffee maker and $7!” - David W.
