To turn on the Lookah Swordfish review vape pen, give it 5 quick button presses. The device will start a preheat function while the lights flash in sequence. Once preheated, you can adjust the voltage with 2 presses of the power button. Choose from green at 3.5V, blue at 3.7V, or white at 3.9V. The three voltage settings allow you to control the strength of your vaping session. The lower voltage setting preserves the terpenes and flavonoids of your wax. As the voltage goes up, so does the temperature which allows you to create massive clouds. When you're ready to dab, simply press and hold the button to enjoy the tasty vapor.
