Two examples of lights that had NMM, in a differnt release batch than original:
Thrunite Ti3
at first they had no memory and would always start on low (as long as you waited at least 10 seconds between off and back on)
if switched off and back on after less than 10 seconds, the light advanced a mode, which could be called NMM, sort of
then one day a friend bought a brand spanking new Titanium Ti3, on my recommendation, because I have one too.
He reported the light had NMM, and would not revert to starting on low, even after sitting overnight… total deal breaker… that light was upgraded to driver VN, to get rid of the NMM “feature”
Thrunite confirmed that was true for that batch of Ti3, they all NMM… these were on Amazon… now sold out.
that made me think the problem was a component that was not identical in value to previous drivers…
I did find a post about a pencil mod that may work for that light…
but Im not sure where it is at the moment
the Astrolux A01 followed a similar version change
first it had no NMM, when it used the Manker driver
but when Astrolux cloned their own A01 driver, they got one of the components wrong, and their version of A01 arrived with NMM
of course many people were unhappy with the “feature”
there is a pencil mod for that here
Astrolux A01 next mode memory removal - Album on Imgur?
my impression is that the pencil mod makes up for the too long reset timing (hours instead of seconds) of the component that was used in the batch of lights with NMM
not on the two twisties I described, they have zero parasitic drain
I think the pencil mod just allows a capacitor that is holding a charge too long, to discharge faster
I dont think these NMM lights were intentionally built to have that “feature”
imo NMM occured unintentionally due to component changes.
I have never heard of any redeeming quality to the NMM “feature”, and I have never heard of anyone that actually wanted NMM.
it totally Bugs Me, and everyone else I know
