It’s Glade Puffy Thing versus Oust Fan…one emits a measured “wisp” of chemicals you can actually see because the normal all-pervasive huffy making-you-trip-your-balls-off stench of air freshener usually isn’t proof enough…the other has a miniature fan that goes all the time.

Personally, I prefer a nice open window and a real fan or a classy candle, but that’s why I’m a liberal media snob I guess.
