“These came recommended to me. I really like them. I only didn't give 5 stars because it says each cartridge is equivalent to about 2 packs of cigarettes, that is impossible. I didn't even smoke a pack of cigarettes a day and a cartridge lasts me 1 day. I also only take about 5 drags of it whereas with a cigarette you take way more than 5 drags per cigarette. However I do like them, they are very smooth.”
