That's because Kickstarter advertises the potential benefits and buries the risks.
If you read their KS page [1] it states: "Pledge $185 or more: COOLEST COOLER: Get your very own COOLEST, complete with blender, a waterproof Bluetooth speaker, USB Charger and all the other awesome features. You will be saving $115 off of the retail price of $299. (Just watch people flock to your gathering when you're the only one with a powered blender and thumping music!). You'll also get the COOLEST Drink Guide and all our updates. (add $15 for shipping)".
Now, you and I know that means "maybe", but does the average backer? I don't think so - honest. It says, right there, in black and white, if I pay $185 I get XYZ. Sure, it says maybe not in the contract, but who reads those? Don't forget home loans in mid-2000. In that case, you heard "HOMES FOR $899 A MONTH!" not so much about the adjustable rate and the potential to collapse your living situation.
Ramble ramble...
