After I've got a build done and vaping it and maybe another one in another atomizer, sometimes I cant remember or cant tell just by looking what gauge wire I used or exactly how thick or tight my wick was before I wetted it...stuff like that. Ihave some 28 and 27 gauge kanthal and even holding each side by side its hard to tell em apart. I've got a magnifying glass on order which may help with some of this stuffWhat little trick???
