Several years ago a friend received as a gift the large Arugula diffuser and whenever I went to visit I told her how much I liked the scent. Fast forward to spring 2008, when I had massive back surgery and was in the hospital for 70 days. Hoping to make my hospital and recoperation time more bearable, she "loaned" me the still beautiful smelling diffuser and I quickly became known by all the staff as the patient whose room smelled wonderful and not at all like a hospital! Recently, I finally purchased the diffuser when I found it while walking through a hotel gift shop; I can't even begin to tell you how wonderful I believe the product is.
