I have been a member of mysurvey for a few years now, and I have always loved how they worked. They have made some changes now that I really do not like very much. They used to offer checks as the only payment, now they do not offer checks at all. You can get gift cards, items, or paypal payments. These payment methods are ok, but all of these items cost more points.
I will still be a member of mysurvey for a long time, because I trust the people that run the site. I do not like the changes very much, but I can always adjust to change. With any online earning site you always have to adjust to the changes that they may make.
