I'm using the itaste vv/vw and aspire nautilus. For the first week it worked great but now it's reading crazy ohms and not hitting right. I've seen it read 7.5 ohms then down to 1.9 then right back to 5.4. I need help cause I'm so frustrated at this point and really don't want to go back to smoking cigarettes. I've been 8 days tobacco free and want to continue this.
