The Vaporesso Corex 2.0 pods (formerly the Xros pods) are designed for Vaporesso’s Xros kit series. 
 
The Corex 2.0 are the new, upgraded version of the original Xros replacement pods and are compatible with the same kits, such as;
XROS Mini
XROS 3
XROS 3 Mini
XROS Pro
XROS 4
XROS 4 Mini
XROS 4 Nano
 
The difference is that they utilise Vaporesso’s latest coil technology - Corex -which delivers better flavour from your e-liquid. These pods can hold 2ml of e-liquid and have an easy top-fill design. Just remove the mouthpiece to access the fill port. The pods feature built-in coil which reduces maintenance, as when the coil inside is finished you can simply swap out the entire pod.
 
Please note, the 0.4 Ohm pods are only compatible with the Xros Pro, Xros 4 and Xros 4 Mini and Xros 4 Nano kits.
