I know this seems to be a popular preference, but I don't really get it. (?) In either scenario, you still need to physically depress the momentary activation switch, either by pushing the DV into the "bottom of the coil" switch, or pressing your finger into an externally-mounted switch ... neither is "hands-free". For me, I actually prefer the external "remote" switch, partly because it "feels" right to me, and partly due to a sense that it should be more reliable over time (and easier to replace, if needed) ... also, there's the "dent in the cap" issue and the "cap getting pushed into and friction-wedged onto" the tip potential issue. The Flix offers both options in one unit - hard to not like THAT approach!If I need to press and hold the button, that's so 1920 (don't get me wrong, it's very interesting, but I believe experience is different). I would really like to see the "modern" option of just pressing it down with vapcap and turning the heater on.
