Hi - it's basically a Vivi Nova clone. You unscrew the lid and pour the liquid inside, tilting the bottle so you don't get any liquid down the center air hole. Screw the top back on. Swish it around a bit so the wicks get wet. Before you screw it onto the battery, take a couple of cold draws through the mouth piece. If you hear gurgling, liquid has gotten into of the air hole. Roll up a small piece of paper towel and slide it up through the bottom air hole (where the screw it) to blot. Take a few shallow draws when you first power it up - that will get the juice flowing up the wicks, so you don't get a dry hit right off the bat.
