I have two friends who gave up smoking for vaping. I tried theirs once, some kiwi fruit flavor juice was loaded, and wanted one. I went the cheap route and bought the NJOY one since there was no shop local to me and the internet searches were confusing and overwhelming. That NJOY worked fine, I guess, but the taste was gross. I went to the site my friend referred me to, but it was for people who knew what they were doing, not a vape dumdum like me, so it was some time before I got around to doing the research and now here I am.
I know it is growing in popularity but wish more brick and mortar stores carried these. i would have made the jump a lot sooner.
