I have used it alot. Its by far a lot more smoke than JTs or Lionel. The scent is not as fowl as the Lionel Premium, but obviously not nearly as pleasant as the various JT flavors.
No harm on any of the components. I don't have a sense of smell, so it makes no difference to me. My wife on the other hand prefers something with a nice scent.
The key to any smoke unit is having enough smoke fluid in it for maximum effects, and not burning up the resistor or batting. 1 properly operating smoke unit on max, will smoke you right out of the room.
