I have tried so many other e cigarettes, this is definitely closest to the real thing which I have been searching for as nothing was making the grade, i also find the fuss of other vapes puts me off, i just want a simple functional device that makes me think im actually smoking the real thing. Small and discreet too, plenty of puffs and the battery lasts. It did take me a day or two to settle on it, a bit of a cough initially, probably a bit to enthusiastic puffing at the start, that only lasted for the first day, no problems now and I have definitely switched from cigarettes, I honestly like it better and will stick with it
