Folks, be careful with this company Runker Inc.  They started with Kickstarter and never fulfilled their backers for their product.  No product, no refund, no communications -just nothing. They took all the funding of a lot of backers and didn't have the courtesy to fulfill their commitment nor communicate with their backers.  Then they set up a website and do a second product!  I still got nothing.  Speaks to the p*** poor ethics of these founders and this company.  You have been warned!
