I do think the Dura runs hotter than other types of atomizers. That is, at least in part, one of the reasons why it provides such a strong "hit."
I keep it frequently topped off so my cartridge is nice and juicy to avoid problems with nasty taste/odor. Personally, I prefer not to think about what it's vaporizing at that point.
Really, my only complaint with my Dura-C is the battery life (1-2 hours, and perhaps even less than that if I'm vaping heavily). But that's really not a complaint . . . more of an observation.
Also, my atomizers are lasting about 2 weeks on average. Again, not a complaint because they give you two atomizers, and you can keep getting replacements for the warranted one for 6 months.
