I've read that the istick will go up to 10 volts, however mine will not go past 3.8 . I've got a .03 ohm coil add I've mentioned in previous posts. And the led display keeps switching from.03 to.04 ohms and the voltage keeps changing. I've already determined this is a counterfeit mod and my dealer is replacing it tomorrow. I was just wondering if this problem I'm having is because it's s fake unit or if it's defective or if this is normal?
