I have tried several different atomizers with my Vamo - they range from 2.3 to 3.1 ohms. My Vamo is breaking them. It happens differently each time - sometimes its on the first use of the atomizer and sometimes the atomizer lasts a few days before it happens. When it happens, the atomizer just stops working and the ohms register as 9.9 on the Vamo. I have tried keeping the power down (seeting the volts at 3 or setting the watts at 4) but this hasn't made a difference. Has anyone heard of this issue?
