I've now tried it at .4 ohms on the TOHB and at 1.2 ohms on the RM2. Gotta say, previous reviews accurate that you get more caramel at lower wattage and more tobacco at higher. I think I prefer the lower ohm build. Going to try letting this steep for a while, but when I revisit I think I'll shoot for .5 or so. Time will tell, but this juice is awesome already
