The Caliburn A2 is so easy to use! This was the main feature considered when designing the Pod Kit along with superb flavour production and nicotine delivery. To turn the device on you quick-press the button 5 times and the same to turn it off. To vape it, you can either hold the button down as normal or simply just inhale. The auto-draw system allows the device to be fired without the use of the button. To fill up, you simply pop the mouthpiece off to the side and fill through the red fill port at the top of the pod. When the pod burns out, you discard it, fill up a new one, wait 2 minutes and enjoy a fresh flavoursome hit once again.
