Hi I am new to this. Please bear with me. I bought one called Mini Cigarette. I started to use it and loved it! I could not believe how good it was! And believe me, I was sceptical. But after about five or six 'cigarettes worth' it seemed to stop working. Oh, I thought, so the cartridges dont last nearly as long as they say ...' It was giving off less and less 'smoke' and getting harder to feel anything. However this carried on even with a new cartridge. Yes the battery was charged. No I did not have my finger over the hole. Now no smoke comes at all, even with no cartridge just the mouthpiece. (they supplied an empty one as well as the cartridges. I presume the atomiser is broken. Is this normal after such short use? Could I have done something wrong? I was SO happy at how good it was and really think I can stick to it, so you can understand why I am dissappointed. Obviously, I am scared to buy another in case it happens again. Also, is the typical description of a cartridge lasting about the same as a pack of twenty accurate? I was even counting fifteen puffs per go to try and make the check accurate. Did I buy a notoriously bad model, and is it better to pay more for a different one? I live in England and bought online for twenty pounds. Thanks for your help. Email me if you like
