The  Aspire CE5 is a bottom coil clearomizer with a dual coil.  

These are bottom filling and easy to set up.  On first use turn upside down, unscrew the base and check the coil is tight in the bottom base.  Fill the clearomizer with e-liquid without overfilling, screw on the base then leave upright for a few minutes to let the e-liquid soak into the coils. 

Removable drip tip, Ego threaded.
