I've been using the iSwitch Maxx for over three weeks now without the craving for cigarettes and to my surprise the taste of cigarettes actually makes me want to get sick. The flavours are amazing, my favourite is Forest Berries but my sister loves the Virginia Tobacco flavour, whichever flavour you'll pick you'll find it not overpowering and leaves you not craving that chemical flavour of a cigarette. All in all once you start you'll be converted instantly.
