be really really really careful .... actually just dont mess with it .... with any of this kickstarter/indiegogo crap. my wife and i have been waiting for one of the various rings from there for well over 2 years now with nothing but delays and broken promises. these people have no business plans, no continuity. they are just random people with no business expertise or experience and have no clue what they are doing. if you give your money to these people and never get your product .... which there is about a 4/5 chance you will NOT get it ... you don't get your money back.
buyer beware. i'm not exactly sure how these sites are not considered scams.
