Anticipation, they look good and of high quality. However, I could often described the "Super" steam generation by Dual Coil not so much notice. That may of course feel each individual differently. To my Kanger MT3S Clearomizer I found no big difference in the development of steam. Same Ohms 1.8 to 4.3 volts. I use it on the new vision Spinner 2, whereupon they look good. But would my Kanger MT3 Clearomizer remain faithful.
