True, but for $5 dollars, this one can be fixed. :-)

Would I want to be supervising it every second it was running in case
the fix did not fix the right thing or in case there was more than one
problem and not all problems got fixed?

One more thing: Cooking of popcorn requires some attention. Its rate
of temperature rise accelerates after it is "done", especially in a
microwave, and popcorn is normally as done as it should get before every
poppable kernel has popped.
Several months ago the Daily Pennsylvanian mentioned cooking of popcorn
as being a major cause of fires in student residences.
Extra vigilence is recommended if you try a different quantity or brand
of popcorn, or a different microwave from one you are used to for
microwaving popcorn.
