The Tumbler is a bottom coil tank made by Smoktech. It has a good strong hit and excellent vapor production. Bottom coil tanks have a superb clean flavor, and reduced wicking issues.
Like the EVOD & T3S by Kanger，the Tumbler has a replaceable bottom coil head.
The product has a very special tank in the shape of bowling pin or lava lamp, which can hold about 2.5ml of e-liquid. There is a vent hole in the bottom of the tank which provides the right amount of airflow.
The top of the tank tapers and thus needs no drip tip. It is a plastic tank so cinnamons and other acidic flavors may not fare well in this particular tank.
The Tumbler has an eGo connector and fits most ego batteries or MODs with ego threading.
