I have been vaping for a little over a month and have used ce6,vivi Nova, and the vivi mini. The vivi Nova doesn't seem to give me the flavor my mini does so I've been leaning twords just sticking with these. I don't plan on ever making my own wicks and replacing the heads is simple. Switching to a carto set up worries me due to going through them every few days from what I've been told being a chain vaper. Any input helps.thanks.
