The Uwell Caliburn G3 pods come with a 2ml capacity and a handy top-fill design, making refilling them a breeze whether you're at home or on the move. To switch between RDTL (Restricted Direct-to-Lung) and MTL (Mouth-to-Lung) vaping styles, just swap between the 0.6 Ohm and 0.9 Ohm pods. These pods have a fixed coil, so when the pod is burnt out, simply replace it with a new one. This ensures vaping remains convenient and easy to manage.
