No light of any color on the batt whether plugged into the computer or the wall adapter. Light does not come on when button is pushed five times as per instructions. Batt was used for one cycle as purchased. Stopped working and will not take charge.
That battery sucks anyway. It gets hot, and messes with the flavor. I got an Istick and slapped the emow on it and saw a big difference. Oh plus the battery actually broke on me
