The first one I bought at a black Friday sale died like 3 weeks later, the store replaced. The 2nd one is working, but is erratic. Sometimes when I try to adjust the settings, the digital display will not move. No matter what i press to increase from like 1.4 on anything. This is if the battery is plugged into a power source or not. Often it goes through all colors-green, yelow, red, for no reason. It seems to burn out wicks REALLY fast. I can go through 1 wick burnt in 1 day with this battery and go through 1 wick in over 1 week with a smoov pass through. I use a vivi nova tank with 1.8 short wick. If course, at the moment, it is working fine. I just put in a new wick. But, it does act oddly, often. I can't get a good inhale on it sometimes after 4 hours of use. I clean the tank often. I dry burn sometimes. Would like some advice.
