I have never roasted my own coffee, but I DO KNOW that air poppers are not even good
at popping corn. A whole lot of popcorn that salt won't stick to. It might be fun for a few
raosts, but I would think if you have a goal, and a goal by the way that is not necessary
to enjoy the final product, coffee, I would save my money for that goal and wait it out to
get something purpose-built.
