I am wondering if because I misplaced it for a week if it got clogged. I have only been using T3's for a couple months and T3s for just a couple weeks...so these are still pretty new to me. I do clean them all every few days but this one I hadn't since it wasn't around. I am trying the extra flavor wick off of a vivi nova coil that died on the T3 that had been leaking. (it is drying now since I wanted to clean it first) On my first try at adding wick was with cotton which a couple months ago that was a big failure..I probably used a cotton yarn that was unsuitable.
