You know, sometimes things go wrong. Its an imperfect world. But I like hearing that these guys are super pro active about backing up the product. I have been looking at one of these hard and when I have the funds to buy my next Vape they are rising higher on my list with posts like this. I have a cheap herb vape that has done its job but am always trying to find more utility and stealth. STEALTH, as I live in a part of the country where they have to pipe the sunshine in. So you guys need to keep us informed of your journey with these pens so we can get a fuller picture. I have bought enough duds filled with empty promises in my day to want to deal with people that are dedicated to building a better mousetrap.
