I bought the vype e pen3, a week and two days ago, I am amazed at how I haven't craved for a cigarette while using it, I was a 20 a day smoker and now started my 3rd cartridge, so impressed I bought another starter kit and 4 more cartridges, from the vype company on line, ordering was so easy, and the delivery was efficient and true to their word. If two cartridges per week, well definitely cheaper than cigarettes I was buying per week. I've amazed not just myself but my friends too as they didn't think I'd stop smoking, never say never!!!! 😁 X
