I take my deck out to rewick without emptying the tank. Just set it upside down.My con on the JK Mini is that you can't separate the deck without the glass tank coming away. Therefore, it's not really an rta where you can pull the deck anytime you want to rewick/build. I don't like that. That and the deck is a pita to thread back on. Not sure this will stay in my daily rotation no matter how much I like the vape.
