I just replaced my cotton, my coils are only a day old, I souked the F*CK out of it and pulsed a few times, wet it again, pulsed it again, wet it again, pulsed off the excess, put the cap on, took a half second test hit and clouded my room like Cheech and Chong hotbox a phone booth. After I got done almost throwing up from the burnt gym socks taste in my mouth, I popped off my cap, and my coils and cotton are still soaked. The f*ck??
