The Aspire ET BDC (BDC means a double heating coil at the bottom of the evaporator is fitted) is processed perfectly and looks classy, especially if you use it together with the same color Spinner of vision. The steam is sufficiently cool and tight (to get denser steam, slowly pull) and the aroma is also transmitted very well, of course, within the means of a beginner model. If one is used in the voltage controllable battery should start the minimum voltage can be set because otherwise the supplied 1.8 ohms may burn evaporator head. To avoid the burnt taste should the voltage be increased only if the device was already some time in use.
