I am having an issue with the Crown .25 coils. Even with the new firmware it is reading the OHMs at .3 to .34. I have also tried to lock the ohms to .25 and with the old and new firmware it seems not to lock. I have the HCigar VT200. Great mod. I wanted to get away from batteries as I fly a lot and TSA has been a big hassle with my Sigeleis and chargers. I have even ordered another VT200. Please let me know what I am doing wrong.
