Works fine right up until you start getting close to the withdraw amount, which is set ridiculously high at $25..at which time I started getting screened out on literally every single survey I took. Sometimes I would only complete a few questions. Other times I would complete the entire survey, and already having been thanked for completing the survey, I'd get screened out..and I was never given a cogent, coherent reason as to why. I would give a negative star rating if it was possible.
