It's fluctuating so badly now that I can't use it. I just ordered a new one from 101 vape. Rock Bottom Vapes had a better price but the site seemed sketchy to me, but 101 Vape had nothing but stellar reviews.
The 1.9ohm coil I've been running in it suddenly dropped to non, then when I fixed it (coil had begun to come loose from the base) read back at 1.8. Then I tried firing it, got nothing. Ohm reader clocked it at .7. Took off the tank (mPT2), cleaned out the connectors, screwed it back on: 1.2. Go to fire, back down to .8. I know it's not the coil, it's been running fine for the past week. My other coils aren't working on it either. All of them were fine on it when I built them last week, I used the MVP to check the resistance and it read them all.
