I think this one is worth passing on.

I'm really sorry to hear that this is STILL a problem with this
product. I've twisted Ron's arm about this several times but the
last time was years ago. There's REALLY no excuse for this from
an engineering perspective . . . we do microprocessor based devices
for airplanes all the time that do not go brain dead during
any kind of normal voltage transient . . . and cranking an engine
is a VERY NORMAL thing to do.
Maybe I need to rattle his cage again.
