Just thought I would write a review to say I have managed to break the current record of 13 months daily use. I have been using the same one, (my first one) since the start of November 12. I have only this month replaced my vapour device, (not due to it being faulty I must add), but because I have replaced all my items, batteries etc due to general wear and tear of daily use for 14 months. Happy to say I am an advocate of Intellicig over other products due to them being a UK Manufacturer and the discreet nature of their electronic cigarette, compared with other models you see on the market. Fully recommend all products. 14 months non-real smoker!!
