The VAPORESSO XROS Nano is one of the latest devices from Vaporesso. It’s the next in the line of pod vapes in the XROS series, e.g., the XROS, the XROS Mini, and the XROS 2. The XROS Nano uses 2 mL XROS compatible pods and incorporates some elements of the other devices while having a nice little personality of its own.
