I've unfortunately backed a project on IndieGoGo for $459 for The Dragonfly Futurefön campaign - and after 2 years, I've never received ANYTHING. No word on progress of the project, no response to my inquiries about the perks NOTHING.
IndieGoGo basically said We cant do anything- you are on your own. So I was been robbed $459 - and that was okay by them.
I even believe that they are a partner with http://idealfuture.com (the company behind The Dragonfly Futurefön).
Don't ever contribute or deal with indiegogo.com!
