What a great device, I was a heavy vaper until now! The device shipped to the Uk from USA with no real problems. There was slight damage to the device in transit which didn’t affect the function but Capnos immediately sent me a new one free of charge to replace it. The box with the device is very well presented. Great customer service and communication with this company. I have been using the device for around five weeks now , there is a pressure valve that releases on the intake of breath, there is a knack to it but it does give you a throat hit sensation. The Yukamint lasted four weeks. I find the chewable mouth piece useful it doesn’t get damaged at all. Best of all no batteries required, no nicotine and no vapour there is nothing else like it that I could find on the market. Because of my Bre-z I leave my ecig at home and no longer smoke at work and only occasionally vape at home. Within the next month I will definitely be completely vape free. I would definitely use this company again.
