Correction:
MM bags will NOT fit in this machine. I meant to write that originally. Sorry for the confusion.
The collar on the MM is way too big. N bags were for the Mighty Mite II, C bags were for the original Mighty Mite, and the MM bags fit the current units that are still being made.
To be fair Les, you did write that MM bags should fit when they will not work with this machine. Just wanted to point that out. There is no need for that kind of language.
