Absolutely fantastic. I've not smoked a cigarette for 7 months now and do not miss it. Thanks to Vype. I use the eStick. It's the only one I personally get on with. If you are moving over to these from cigarettes don't be put off with the taste of the cartridges that come with the starter pack. Try other flavours before giving up. My personal favourite is the vanilla or neutral. I smoked for 35 years and these are the only ones that work for me. Think Vype would be better off sending the starter packs with neutral as the taste of the tobacco has put many of my friends off continuing to use it, which is a real shame.
