Just purchased the Vype epen 3 to help me cope as I quit smoking cigarettes just 4 days ago. I smoked 1 pack of cigs every other day for a very long time which was costing me a great deal of money :( I tried quitting numerous times with no luck. I have tried a few different e-cigarettes and none of them compare to this Vype pen. I LOVE IT! I love how I can change the cartridge flavors so easily without any hassle or leakage! I love the amount of vapor I expel! I haven't craved a cigarette for 3 days now! I am super happy I bought this pen! loyal client from Canada!
