Here is a new invention that has been a long
time coming. It was a kickstarter campaign and garnered US $4
million. The goal was $160,000. If it makes it, a whole industry
will change forever, just like it did when Gillette came up with
the disposable razor blade. This one is non-disposable and
requires a battery to operate.
Kickstarter has suspended funding because it is, “in violation of
our rule requiring working prototypes of physical products that
are offered as rewards.” Should be fun to watch for the next
round. See for yourself at LINK.
