Vaporesso XROS 3 Mini Kit. All you have to do is puff on the mouthpiece, which will create a moderate amount of vapour for an RDTL style vape that has a tighter draw feeling. You can also find MTL (Mouth To Lung) style XROS pods which are all available from the Vaporesso XROS range, if you prefer a more discreet amount of vapour.
