We have tied and tested the Caliburn G 2 and the verdict is... this device is one of our favourites. A super-smart device concealed in such a small package. The haptic feedback is a neat feature you don't really see anywhere else. The coils are really good and there is an option for users who want lower power for high nicotine but also for those looking for a bit more but still want a small device. Flavour production is also very good and the fact that you can monitor your e-liquid level at all times is a big plus. You also get adjustability via the airflow-ring on the pod to further adjust your vaping experience.
