???  And what is their production volume?  If they sell a good (or even OK
product) at a good price it will sell in volume.  There are lots of
applications where people want their pis to stay up 24/7.  Before I bought
this thing, I'd buy a proper UPS that will also power other devices.  This
also isn't exclusive to the rPi.  It can work with any embedded system.
