So I dont know if any noobies like myself have done this, but I decided to switch out a kanger tank for another one, just to change the juice flavor....well I guess I unscrewed (sorry dont kno the tech names..) the bolt thingwith the tube in it from the clear part, so all the juice spilled out onto my pants..lost some good juice and dont kno how the pants will fare...just a heads up if anyone is goofy as me..make sure you unscrew the whole piece together, or you're gonna get wet...:-[
