Like the title says. I have a few vw box mods and have been running my tugboat v2 with a dual clapton at. 5ohms. Got my first mech today(copper nemesis clone). Same build in my tugboat and same juice I've been using on my vw mods. I get a hotter, denser and more flavorful vape with these. Tried my mech out and it's very "airy" and the flavor is soooo muted. Like breathing in air. Good vapor production, but can't feel anything while inhaling/exhaling and flavor is almost nonexistent. Fully charged battery reading at 4.1v via multimeter. Thanks.
