I do not smoke. It has only been used at home. While it worked fine when I used it before, it hasn't been used for nearly a year, and I don't have anything to test it with. Therefore, please understand and only purchase if you are okay with this. I believe the condition is relatively good, but please understand that this is a used item and accept it as-is, no returns.
