Notwithstanding the fact the product is based on false assumptions, Batteroo looks like the perfect example of graduate, boardroom 'engineers' that have never actually done any practical work, hence no experience in testing and engineering for production. A lot of talk, but no delivery.
I doubt their initial intent was to defraud, but they simply had very little idea what they were talking about from day one.
About now, they should setup a roadside lemonade stand that offers to swap out the batteries in children's' toys! ...but health certification for the 'Kool Aid' substitute may be difficult with the track record of Batteriser... at least 'staying on the shelf' due to delayed shipping, it will last much longer than real 'Kool Aid' !
Perhaps one of the backers could ask which 'products' were tested at 2, 4, 6 times extended operation, and the testing methodology.
Of course, these tests are irrelevant with new chip design/silicon coming 'soon'...
Sigh.
