They provide serval survey sites for you to let you complete a survey so you can get a lot of survey here. I have already cash out 2 times and have no problem so far. They pay you very quickly, for me they took only 1 day to send the money to my paypal account. Also they have different reward like visa, amazon, steam, paypal and more...
Ohh and other thing I like of them is that, they always tell you the process status --> you will get 3 email from them
1. To tell you that they received your request
2. To tell you that your payment is being processed
3. Money received!
