From Kickstarters own web site:
What everyone should know:
Kickstarter is not a store. People aren’t buying things that already exist — they’re helping to create new things. Creating things isn’t always easy. Some projects will go wonderfully, and others will run into obstacles. Be prepared for a little bit of each.
Creators are responsible for their projects. When you back a project, you’re trusting the creator to do a good job, so if you don’t know them personally or by reputation, do a little research first. Kickstarter doesn’t evaluate a project’s claims, resolve disputes, or offer refunds — backers decide what’s worth funding and what’s not.
Some projects won’t go as planned. Even with a creator’s best efforts, a project may not work out the way everyone hopes. Kickstarter creators have a remarkable track record, but nothing’s guaranteed. Keep this in mind when you back a project.
