Coils are on an Igo-w. Meter reads out at 1.5 ohm. Vamo says they sure 1.5 ohm and gives no errors. Coils aren't touching anything. Legs are good and snipped flush to the posts. I can even crank up the Vamo to a max 15 watts. They warm but will not glow. From what I have read, the Vamo limit is 1.2 ohms. The nautilus coils I run are dual at 1.6 ohms.
