Does it work well, or is it one that you need muscles to operate?
Of course it is going to take some effort. We have another one that is harder to turn. It doesn't take long to crank out a cupful for cracked wheat cereal. I have not actually timed it. We saw this one on display at a local store and they had wheat there you could grind. It was so much easier to turn than the one we had, so we bought it.
You need 1/2 cup of cracked wheat and 1.5 cups water per serving.
