Have tried to quit smoking before but only lasted a week or so. This time I am now at 4 weeks and all going well since I have used Vype (was a 20 a day smoker). The most impressive thing about Vype compared to others is they don't seem to leak hardly at all. I used to find others (socialites and cirro) leaked in my pocket which was very annoying. Battery life is good and gives good warning before running out (stays on amber for a long time before it goes). Only issue I have found is trying to find tobacco flavoured 18mg liquid in shops and have had to buy online. Highly recommend though and my sister has already swapped to Vype after my reccomendation.
