I'm MTL - don't really know how you DTL. but pretty sure I don't want anything that hot getting too far in! Maybe this is just the wrong kit for me and I should stick to something simpler - it's very unpleasant, and after a few presses, too hot to hold in my hand. I seem to getting liquid rather than any vapour. Bought it direct from Smok Tech via Amazon, but it says the order was fulfilled by MKWS (100% feedback). Maybe I need to do that authenticity thing on the little card in case it's a clone.
