Who runs the panel

ePinionCenter is a market research survey panel that gathers the views of everyday consumers. Businesses and research firms use the feedback to understand what people think about products and services, and the panel links those requests to the people most likely to respond. Panelists join, complete a profile, and are then invited to surveys and studies that fit that profile. The work centres on giving ordinary people a regular voice in how products are developed, so opinions keep flowing between participants and clients.

Privacy and member security

Members are asked to keep their access details private and to report any suspicious use promptly, since they remain responsible for their own membership. Personal details such as a demographic profile are used to match research, and that information is kept secure and never sold. Before a member's answers are approved, the platform may ask for proof of identity, age, residency or other details. Those checks protect both the members and the research clients who rely on accurate answers.

Eligibility and membership rules

Membership is limited to adults who live in the United States, and each person may hold only one membership unless the company agrees otherwise in writing. Membership is meant for a single person, so sharing or lending access details is not allowed. Members agree to give accurate, complete information and to keep it up to date as their circumstances change. The company may suspend or close a membership if it suspects that the member is underage or has broken these rules, which keeps the panel focused on genuine participants.

Who the panel is aimed at

The panel is aimed at people who enjoy sharing opinions and have spare time to answer questions on their own schedule. Studies can be taken at a time that suits each member, which makes participation flexible for people who work around other commitments. Members who like variety will notice that studies cover a wide range of subjects, from everyday products to fresh concepts. Keeping the profile current helps the matching work well for each person, so the studies they receive stay relevant over time.

Our full take

ePinionCenter is a market research survey panel where members sign up to take surveys and earn points that can be redeemed for cash.
