The m80 pro has gone to the wayside since smok has released newer models, they do offer updates but they don’t correct any of the real problems other than the squealing noise the early versions had.
Doesn’t down regulate/step down well & uses PWM until it reaches a condition that it can down regulate semi accurately.
The temp control doesn’t work.
Updates do not correct these issues.
Many folks like them, if you use it in W mode it is an okay power device.
I understand you have a Pico, all the feature & modes work correctly, I’d consider the m80 to be a back up & spend time getting familiar with a device that functions correctly.
