The vapour does not smell nor does it contain tar, arcinogens or smoke particulates found in first and second hand cigarette smoke, but it feels, tastes and looks just like the real thing. Best of all you can "smoke" your nicotine machine virtually ANYWHERE! Twisp electronic cigarettes represent the very latest technology in micro vaporisers, being the smallest, lightest and most reliable on the market. Beware of imitations! Backed by our 3 month warranty, your Twisp electronic cigarette should pay for itself in less than 6 weeks, not to mention the benefits of not inhaling tobacco smoke.
