Just one cube of the wax melt filled up my entire office, drifted down the hallway and into other offices as well. I was shocked at how strong the throw was. The fragrance is also lovely - a very SWEET, yet tart apple is predominant, rounded out by the sage. I wish it was a touch more green & herbaceous, but still an enjoyable scent. Much better for a large/open area than an office because of the strength.
