I have an Infinity Pro and I'm looking for a rebuildable atomizer tank that looks good on it. All the ones I have look funny because they leave a "wasp waist", as you can see in the photo below. I saw the Steam Machine Gini has a recessed connection. Would it physically fit on my Infinity Pro? Has anyone successfully used other eGo-threaded atomizers, like a Stardust or Kanger?
