They already said they just recycled their ASG series (which is obviously much more fragile) warranty for now. The product is not done or else they couldn't put it on kickstarter. Before a true warranty decision gets made by a company they get finished products, usually off of production tooling, and go through stress testing to determine when/where they fail. Until Aurisonics is able to do this you can't make the generalization that their warranty directly speaks to the quality of the product.
I'm reminded of a great quote "they know all they sold ya was a guaranteed piece of $h**. That's all it is, isn't it? Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for now, for your customer's sake, for your daughter's sake, ya might wanna think about buying a quality product from me."
