Janty: mini fogger or Dura-c??

Hi guys,

I'm new to e-cigs and, after much research, have settled on either the Janty mini fogger OR the Janty Dura-c, but I can't really see a difference in them (other than the auto battery on mini fogger and choice of either kind on dura-c). I do notice that everywhere I look the mini fogger seems to be a few bucks more than the dura-c, which tells me that their must be some kind of difference in the two but I just can't see it.

If someone has used both of these, could you please let me know what your "consumer comparison" opinion is?

Thank you
