When i use the
device i don't want to accidentally change the wattage. When i pick it up, or when i'm
vaping, i sometimes hit the + or - button without knowing it. This happens sometimes !.
I understand that locking the device is most practical for when it's not in use, in a bag or pocket. So for most users the lock function "should" lock the fire button, and that would make more
sense. Having said that, if the device isn't in use, then turning it off is something a user would do. Why have a lock function which leaves the device on but still can't be operated ?.
The instruction manual says one thing but the device does another.
