Great service for sociological surveys. Here, businesses get information about the interests of customers for goods and services, while respondents can earn a little money. The results come to your phone from 450, quite quickly, in about a week and a half. The surveys vary: some are completed, while others may not take place, as you need to fit the sample. Additionally, every day there are small surveys with a little payment, for example, to evaluate packaging and products, around 10 items.
