Replying to Crowd funding... Indiegogo vs. Kickstarter?

Putting together the finishing touches to all the financial and construction details to a product for a crowd funding campaign I hope to launch within the next week or two but I was hoping to draw on the experience of the collective before I set the ball in motion.

Indiegogo and Kickstarter both seem to be nearly identical on the surface, is there a difference once you get into it or are they the same thing? I've never financed anything through crowd funding before but I figure it would be perfect for what I'm trying to do with this product. Any experiences or insight you could give me would be greatly appreciated, thanks!
