Well the ones i posted a link to are fillerless and that appears to be what Pocha was responding about.
The ones i was referring to are fillerless and new so i doubt you ever tried both of them in the distant past.
They still look EXTREMLY similar in design and function to a SMOK DCT ProCoil hence the similar IKV name {ProCoil). Who is the only company that commonly manufactures and sells dual coil cartos?...SMOK maybe because ive seen no others in any quantity ever?
My money is on they are identical rebranded SMOKs. Considering Boge (the IKV former supplier)and SMOK make over 90% of cartos, its a damn good bet. Who else would you imagine makes them?....Kanger?
I really cant see SMOK or Boge doing much retooling to a Chinese factory to accommodate the specs of a relatively small supplier in the states. The lack of current availability speaks volumes to this conclusion.
