Recently bought the Vype e pen 3, must admit having tried lots of e cigarettes it is the closest I have found to a real cigarette.
I have not totally given up the Fags but this machine is helping me more than any other so I hope to be fag free very soon.
Very easy to use good charge on device and would say only draw back is cost for a pack of two cartridges but if you are offered discount codes it helps keep cost down but highly recommend.
