I am an investor in smoke free and a smoker. I got my kit Saturday and tried if yesterday for the first time. The jury is still out. I have a vapor one and I am use to the smoke or vapor when exhaleing. Not sure this is going to do it for me, but I like the idea and love the stock. I am going to keep trying it and see if I can really switch. My only draw back is exhaleing something. Anyone else get one and try it yet???
