These smelled great in the package. I plugged them in, one in the bedroom and one in the hall. A few hours later I went upstairs and was really confused by the scent, it was body odor mixed with pipe tobacco. I though I might be crazy, but when my husband came upstairs he said the same thing. I thought it may have come from outside but today the smell is still in the house and worst than ever. I threw away the airwicks and bought new ones, the smell is finally going away.
