I bought a 51 impulse buy. I do like the idea but do not like the smoke to much that they give. I am thinking of buying a diffrent unit but do not know what I need please help. I am a 1-2 pack a day guy. Also is this safer then actual smokeing. They say it is water vapor. But then I read it is anti freze what gives? Please post a link of a place I can get the things I need to get started. Thanks.
