Have you received an email from the address no-reply@s.backerkit.com with the subject “Response Needed – Get your reward for Philips PicoPix Max - 1080p Full HD Pico Projector”? The message contains a link to a survey, which you need to fill in. If you haven’t received that message or have not filled in the survey, Philips doesn’t have your address yet and they will not be able to ship the projector to you. If I understood correctly, those blanks in the list refers to people who haven’t submitted the survey.
If you backed the project recently, they might not have sent the Backerkit survey to you yet. Otherwise, you should have received it by now.
