[This review was collected as part of a promotion.] So I got this as a free sample to try in exchange for a review. It works just like any other Glade Plug-in Oil refill would, with regards to functionality. The smell was nice. To me it came off as a light and clean smell, which is different that what I expected and what I was used to. I normally prefer sweet or heavier scents so this was a surprising scent for those who come to my house. I expected it to be sweeter with the name Cotton Cloud Dream, but it was overall a nice scent. I would recommend this to a friend, but not necessarily buy this specific scent for myself, due to personal preferences.
