I like and still use my eVic daily, but it's always kind of irritated me that there's what feels like a 1/2 second delay from when I hit the fire button to when the coil gets the zap. I'm hoping the Supreme doesn't do this.
The innokin 134 does that too, the explanation is that the chip checks the resistance of the atty each time the fire button is depressed. I've just gotten in the habit of pressing the button as I raise it to my mouth.
Actually that habit got so strong that i always do that now, no matter what I'm using...not necessarily the best thing but whatev...
