I'm happy to report that
Mindfield Online is most definitely legitimate! They payout via check, PayPal, or Amazon gift card once you've reached a very easy $5.00 minimum. They pay you for your opinion, it's really just that easy!
Mindfield Online usually sends out one to three surveys a day that range anywhere from $1 to $25 depending on the type of study. The surveys are usually pretty short and usually only take 10 to 25 minutes to complete.
Mindfield Online is a division of McMillion Research, a very honest company that has been around for almost thirty years. They are also members of many of the trusted marketing research trade associations including AMA and CASRO. I highly recommend this reliable, honest company as a great way to get paid for your opinion online.
