I can't believe I'm hitting this thing while all else sits for a while. You can pop off the silver bottom piece easily, and then rewick it and soak clean the coil too. It Def works better after the rewick. The cotton on some of them from the factory is too tight in the coil. I'm surprised by the nice airflow and amount of vape at about 15 watts. Great flavor that rivals some of my twisted or clapton built rtas. It just takes a fuew minutes to rewick it, so I vape it for 2 days, then rinse the coil before it's bad. Then rewick. I'm digging the hell out of this little vape. Yeah..till it dies next week lol
