I was very skeptical if the fog is very dense as promised, but he's really, felt almost twice as dense as fog normler. In the New Year's party the room was with only 3 sniffer dogs to misted completely, while I have only a 450 watt fog machine (ADJ Minifog). So who stands to dense fog can access calm. Although the smell is not unpleasant but I would nevertheless add a fragrance.
