OK so loads to learn and try but have mastered the difference between having a vape and having a fag. I have two units already both fixed output, one was the Switz2 that the kids bought me and that has replacement coils, I also bought a budget unit so that I could use clearomiser tanks (10 for less than a packet of fags) to try different flavours in. Tanks on order. Currently low cloud and low nic - happy with that at present. Have tried 2 flavours so far and only like one. Happy with the nic free Menthol that I am trying in the budget unit, but dislike the low nic Tobacco flavour- Its not the nic level - just don't like the taste. Family have bought me some other flavours to try so waiting for the extra tanks.
