For this specific atomizer with 0.7 mesh coils, I put two rebuildables in the drawer that I was using and couldn't fully get me away from cigarettes. The Nautilus managed to do it and even without effort, since with the mentioned coils, the flavor, the hit, and the amount of vapor satisfied me completely. I read comments about overconsumption, but the atomizer consumes what it needs for the vapor it produces within reasonable limits. If it doesn't consume, how will it produce? Zero leaks and easy refilling once you get used to it after two days of use. I used my own drip tip and a 4ml capacity glass from the beginning. I highly recommend it to both new and experienced vapers like myself who are tired of struggling with rebuildables
