#5 - I started with a Vapor Zeus for 1 month, then found the MVP2 and used it for3 months, now using the Eleaf Istick . I quit smoking cigarettes the first day I started vaping. I smoked cigarettes for 45 years, 2 packs or more a day. I tried every way possible to quit but nothing worked until I tried vaping. 5 months cig free and feel so much better health wise. People tell me I look better also.
