I have smoked for over 40 years, tried to quit many times with no luck. My wife and I were on a boat cruise in Jan. where we met a nice lady using a White Cloud. She gave you such great reviews that we had to give it a try. We started with the Flings and then bought the Cirrus kits. It has been almost two months since either one of us has smoked. We both feel so much better already and the money we have saved is wonderful. Your customer service is great, 5 shipments so far and all on time and no problems. I tell everyone I know who smokes to give them a try, a few are doing as well as we are. This product works and I like the ISO certifications you have. If the FDA ever does regulate, and they will soon, it is nice to know that you are trying to comply. My son goes to a local vape shop, it is nasty, God knows what they put in their "juice". You should really promote your ISO certification and compliance with FDA, makes me feel better knowing this. I have tried the flavors, just not me, but having not smoked for almost two months says something. I am not gaining weight, I am not irritable and I do not crave my old cancer sticks. My sense of smell has almost returned to normal. My children and grandchildren say I do not stink anymore. No one around me complains about the smell or odor from the Cirrus, most tell me they cannot smell anything. Please keep up the good work, I am certain that just the R&D involved is difficult. I have tried many others, yours are the best I have used.
