Here's another company to add to the list: Insinkerator

I bought one of their instant hot water dispensers for about $175.
Just outside the one year warranty,
it stops heating the water. Upon taking it apart, I find out the high
temp fuse has opened. I call them up
and find out that the replacement is a kit that changes the design and
now uses a very different style. Looks
to me like they figured out the original ones were defective and
blowing for no reason. Still, I wound up paying
about $25 for a new one plus shipping, as they wouldn't replace it out
of warranty. Next time when I have a
choice, you can bet it won't be Insinkerator.
