I honestly don't get Kickstarter. Basically, what it is is a venture capitalist venue for dummies. And I mean that in the most pejorative sense possible.
Kickstarter projects are by definition rather high risk ventures. You are investing into something that is being built. But people treat it like they're just buying something that IS already built, albeit with some rather insane delivery times. That this has to lead to disappointment is a given.
There is a pretty good reason "ordinary" VCs want equity when they back you with money. They are carrying the risk together with you. And there is a pretty good chance that the money is gone because the project never materializes. They accept a high risk, so they want a high reward. That's sensible.
What people on Kickstarter do is to accept a high risk for a pittance of return. What do you usually get? You get the product they try to produce. Maybe at a reduced price (read: at cost), maybe in some superspecial edition that ONLY backers get (and everyone who later pays a buck extra).
Sorry, but if you accept that deal, you better have other reasons to back the project (like, say, you really, really want to see this done and you love it SO much that you'll willingly throw away money for the CHANCE to MAYBE see it happen).
