30 days with my 3 Intense RDA's, using 12mg Tobacco juice, usually at 20 watts with restrictor and peek cap set on paired holes. Compared to my Profiles the Intense at first seemed a bit mute but after many compares I think not so much flavor as throat hit. Usually I ditch a atty I don't like inside the first week but for some reason they have stayed around, not disappointed, more of a mtl then dl. I like the easy build, no-leak design but the deck really does get warm.
