I got a 1.3 now and was doing 12.5w and getting dry hits. I am using a squape on this one. Tried to rewick it and lifted the coil some and still dry. Gonna have to keep playing with it. Hate that vacation is over now. Lol but I did do a nice one in my kanger I think it is. 8 running at 16 and it is a dream.My coil is 1.5Ωs and I run it between 12-14 watts either w/ a KFL lite or KFLV4.
