After a campaign has successfully ended, backers of the project will see a banner at the top of the project page with a ‘Your Voice Matters’ section. Here, backers can select from one of three smiley faces in response to the question, “How do you feel about this project so far?”.
This feedback feature allows backers to share their backing experience with us for any successfully funded projects they have supported on Kickstarter, and their responses may be shared anonymously with the project creator.
Can I change my feedback selection?
The ‘Your Voice Matters’ section resets after 24 hours, so if you return to the project page after this time you should be able to select a different smiley face.
