Review is operated by The GfK Group, Germany’s largest market research institute and the 4th largest market research organization in the world. GfK stands for “Growth from Knowledge”.

Members are asked to fill a short questionnaire to determine which surveys are most appropriate for them. Two to three survey invitations are sent per month. Members who complete each survey earn points which can be used to redeem various rewards. These rewards are displayed with each survey invitation.

All points expire 18 months after they have been awarded and credited to the members’ account and when the member has become inactive. An inactive member is one who has not  been taking online surveys  or attempted to qualify and complete  at least  one survey within a period of  12 months. This means any unredeemed points will expire immediately without notice and the member’s account may be terminated.
