I only got burned on one, which was the NinjaSphere. Unfortunately it was one of the most expensive ones I backed because I went for the developer kit ($500+).

I only got burned on one, which was the NinjaSphere. Unfortunately it was one of the most expensive ones I backed because I went for the developer kit ($500+). Though I did actually receive the developer kit.. became next to useless very quickly. Other than that I seem to have chosen my kickstarters pretty well and very happy with most of them.
