Hi folks, I'm about 3 months into
vaping at this point. I've used the penstyle, riva/ego varieties and have also put together a 5v box mod. I've been looking into tube mods lately and am curious what suggestions you folks would consider your favorite in the category. I've been mainly looking at the 18650 varieties and interested in trying out a stacked 4.8v NiMH with it.
