I registered on this website few years ago and started taking surveys. Till now I have taken around 20 surveys. There are different points for different surveys but the length seems to be same for a 500 point survey and a 1000 point survey.
It takes a huge time investment and patience to fill up the questionnaire. Moreover, many times after filling screener questionnaire, they disqualify to take up the main questionnaire. Sometimes they don’t transfer earnings into bank account, vouchers etc. i.e earnings get lost somewhere in mid.
The mobile app of the website hangs a lot and is not good, it requires improvement.
