I have both well the Nano and turbo, the Nano can handle anything you throw at it. the turbo the coils cant handle over 18 watts get a burn flavor.
and the turbo is massive not really for everyday use, more for just to play around with i set the watts at 18 and took a huge lung hit it almost killed me.
tons of vape it is a fun tank but i would take the Nano anyday.. i was gonna try today and see if 2 of my nano 1.2 coils will fit in the turbo if so it will be the monster of all monsters.
Coils dont fit if the turbo was bigger around with enough room they would fit, wonder how long it will be before they build a Quad coil subtank.
