I really think it's not Smoktech that has problems. I believe that
madvapes is selling knock-offs.
madvapes was selling the 2.0 ohm dual cartos, as Madvapes brand. Then the consumers were complaining about the performance. Then I seen Smoktech 2.0 duals for sale, along with the Madvapes 2.0 duals. Then after they moved, then the Madvapes version was gone, and the Smoks 2.0's had much more in stock. As for the dct replacements, they don't list them as Smoktech. It makes me wonder, what are we paying for????
