Should work fine, have you tried lowering the watts? Try 15 and work up. Also check connections between atty and device to see if it's got juice in there.
Cool, I generally don't go above 18 using a single coil set up and the type of juice I make. I don't need massive room filling clouds, I only want to replicate the hit I used to get from a smoke.
The shop bought juice hit the back of my throat with a nice belt no coughing with an easy draw,.... however the juice cabin stuff is hard to suck in plus makes me cough like mad
