All of these points are valid to one degree or another. There are a few that I have minor issues with, such your use of the word "bomb". None of my
mods are tubes, and none of them can build any pressure from a venting battery. So "incendiary
device" perhaps, but "bomb", no.
Yet my choice of mechanicals does have some advantages:
- Mods that do not fail randomly and in wonky ways such as suddenly deciding to produce a much hotter vape than expected because the mod mis-read the resistance of the coil or the input for the Up button thinks the button is always pressed even though it's not. I've had both of these happen on DNA mods.
- Mods that can be fixed rapidly with common hand tools if/when they do fail.
- Mods that I'm absolutely certain will work if I pull them out of storage one, two, or even more decades from now.
For someone like me who is perfectly content with builds optimized for ~3.7V and for whom a single 18650 lasts through a 600 mile, 9-hour drive with capacity to spare, they are a good solution.
Oh, and cost had absolutely nothing to do with this choice.
But to each his own vape.
