I smoked 50 years, only the lightest nicotine recent years with 0.1. 1st dampftag 3 half smoked and disgusted. I can not believe! since about 2 weeks no desire to smoke more. I evaporate without nicotine and without lung trains. a godsend. the device is easy to fill in for me and are, so I think a lot of steam. am very pleased with the set.
