You can join the referral reward system for backers. Let me know your email after you back the project here. You will then receive an email for you to introduce the product to your friends who need it. Once your friends have backed it, you can come back here to fill up your friend email. Or you can ask your friends to fill up. I will verify your friend email at Indiegogo and then both you and your friend will have the referral gift in the parcels.
