As a road cyclist who rides with a lot of other keen amateur cyclists, very few of them, well actually none of them, that I know, smoke or vape, except me. They all look at me with a mixture of mild curiosity but mostly with disdain and concealed disgust. I would be surprised if any mountain climbers or recreational climbers are likely to be vapers. The idea of a device aimed at sports people seems to be a bit of poor marketing but. good luck to them.
