I understand Nubee, and I also like the idea of the smaller one but there isnt any way tooffer 5 to 6 volts without dramatically increasing the width of the entire unit and adding joints to the construction...Once you vape at 5 and 6 volts you will change your mind about the length maybe!!! But for those wanting all the voltage options without rebuilding when changing voltages this is a better design that allows both as a more economical obtion...Thanks for your interst...
