Have just bought one to replace a well used Ijust Start+. So far I have put in a 0.75 GS type coil (in the sleeve provided). First impressions are, well, this is superb. Despite looking harder to clean than the 'start' (tank is sort of attached to the base) it has great promise. Flavour wise it is the best I've tried. (Out of Ijust Start+ and surprisingly Istick Pico as well). I will give it some more use and update as I get used to it.
