I don't use it much anyway but I have been using the same clearomizer which is disposable so its coil has been the same the whole time but each time I unscrew it and screw it back on the lcd screen reads different ohms volts and watts (it didn't always do this) I have the Apollo valiant battery Apollo Valiant VV & VW 1300mah Battery Have any of you heard of similar incidents before and know how to rectify the situation?
