I am wondering if there is anything out there that fits what I am picturing. A vv or vv mod with replaceable batteries that has the simplicity of a mechanical mod. No screen for settings just something simple like a twist dial. A very simple tube mod that you can adjust is what I am looking for and can't seem to find what I am picturing. I have a kanger vv twist now but really like the look of the mechanical mods but don't think they would be right for my nautilus mini I use. Any help would be greatly appreciated.
