Please read the bad reviews before coming here. Very inconvenient. The way they pay you is that they give you a card which cannot be used anywhere else. When I try to take the money out it charges me $3.50 every single time I take money out and I think the maximum amount is 400 and 500. I end up paying not only taxes for doing the study but I get to pay a lot of money just to take my money out too. A ripoff.
