Hi, My first RBA is a phoenix clone, and I finally made a coil that is successful. Meters at about 1.9 ohms. After 2 days of breaking in, it works really good. Using epipesmod.com liquid and Spinner at 4.1 volts. But when I take 3 or 4 draws back-to-back, I notice the housing gets really hot. Common sense says put it down for a bit and I do. Can the atomizer get too hot and cause any problems? The unit is made of chrome plated brass and is called a bulldog.
