I'm not sure, Fonz. Why don't you ask a supplier who carries both the M201 and DSE801? For example, shawnp1 (his ECF screen name) of
LiteCigUSA. On this subject, he (or people like him) would be the "expert." And I suggest that you post your query in his supplier forum (and/or in the
M-201 *Penstyle* Model Specific Discussion forum) to pick the brains of a group of folks with first-hand knowledge.
Sorry I can't be of more direct assistance. Hopefully those leads will provide you the answer. Aaay!
