Why would you not recoil after you've vaped all the juice out? The K4 is for the hard core enthusiasts who want to monkey around. I've had enough building experience where I'm past the monkeying around phase. I build it, it works, and I don't need to look at it again until I'm ready to dry burn and change the wick. That always happens at the end of a tank when it's already drained. Just don't get it Dust. They want a hefty price for that thing and I'm simply not seeing any one thing that improves flavor or vape quality (at least the P3 gave us the boost feature that significantly improves the vape experience). That air adjustment is cheesy too. If I'm talking to Robin, I tell her to save her money. And is it that hard to drain your tank that makes it worth $200 to upgrade to a K4?
