I am shocked by the amount of reviewers complaining that the project they backed was delayed. Get real. Kickstarter is not a store, you know. You are not buying a product, you are investing in a project. You are taking a risk. Some projects can be delayed or even fail, because their founders failed to predict all the complexities of bringing an innovative product to the market - and there are many. It may or may not be the fault of the project creators, but in any case it's not Kickstarter's fault. Kickstarter is a great place to fund great ideas, just understand what you are doing.
