Hi Brian,
My name is Jamie Camp a couple of months ago I purchased a Mark III "Scallywag" . It is a beautiful mod with the Turquoise inlay. However, it wasn't so great for my style of vaping.
I am pretty much 901 user and when I am not using 901 s atomizers I like to use the Smoke Tech Dual Coils . Unfortunately, neither of these really work with the Mark IV. I wrote to you back in June about this and you very generously offered to take back the unit either for a refund, or for some modifications. Well, shortly after that, my work caused me to have to go over and spend some time in Europe from which I just returned.
