“They always send links to me to participate in surveys, but 70% of the time after I click the links, it says "Survey is no longer available". Because of this, it takes me more than a year to accumulate enough points for redemption of rewards.”
“There are not many surveys available on OpinionWorld (For my demographic at least).
In the same amount of time that I registered for other sites, I've cashed out rewards multiple times from other sites, but only once from OpinionWorld because that's how little surveys I was getting.
However, I did receive my reward just fine and will continue to use OpinionWorld when a survey does come out.”
