They make it sound like you have to use these on only dna device. Could that be true. Why would they not work on any temp sensing mod. I have the sx mini m class . I love the nautilis coils and would love to try them. They say anything but a DNA 40 device will damage the coil. Is this true are or they trying to sell you a DNA 40 device. I don't remember if they said those about their nickel coils for the subtank. Any thoughts on this. I would think they would work on any temp controlled device.
