I quit 20per day cigs 9 month ago... immediately replacing it with smoko e-cigarrete. What I really like is how affordable this option is..... a cartridge a day cost me £2 (cigs cost £14). The e-cig is pretty descreet.... doesn't smell like some vaps can .... nor does it blow out big puffs of 'smoke' like some do. I was extremely surprised on how well this replaced nicotine so I didn't crave fags. Big variety of flavours. I've always got mine in the post the following day. Truth be told .... if I'd known this was goin to work as well as it has ... id have quit smoking a lot sooner !!
