I fitted 306 atty on M40x batt w/ an adapter.
Now I can enjoy M40x w/o that tuff draw; draw easier than analog.
M403 producing equal TH, vapor and flavor as big batt Roughstack!
Of course the batt life is more on Roughstack.
Works great on M401 PT.
Performance seems equal to Roughstack even though Roughstack has higher volts.
M401 PT = 3.3volt no load.
Roughstack = 3.7 volt no load.
I tried 1.7ohm and 2.5ohm 306 attys.
I'm more comfortable w/ 2.5ohm.
Not sure how much current M401 can handle.
2.5ohm 306 atty produces good flavor, TH and vapor.
This is the closest to analog I've found.
Drip tip is great for hands free vaping.
