Have had mine since before a year ago Christmas, it's all I vape anymore. All my carto's/tanks are clear. Latest is the Vision Stone w/screw on end caps. Been waiting for screw in caps for forever. Should eliminate the involuntary tank dumps. Love the Stone so far, my first pair read 1.7 ohm on ProVari. JMHO
