Mindfield online surveys promise on their web site that it is an easy way to earn extra income. However, my opinion is that it is not easy. In order to participate in their surveys you must first fill about 8 “profile” surveys. My feeling is that these surveys in fact lowering your chances of receiving surveys. Not only that, these profile surveys expire after a while so if you did not log in for a while, it is possible that your profile surveys expired while you wonder why you are not receiving any survey invitations. In addition, like many other survey companies, your earnings are kept in a “Mindfield account”. You can ask for a check only after you reach 10 dollars. After over a year of filling Mindfield surveys my balance is 3 dollars and I doubt I will ever reach the required 10 dollars.
Frequency of surveys: once in a couple of weeks
Average pay for survey: 1-2 dollars. (if any)
Remarks: There are easier ways of making money online.
