Its a huge rip off! Originally febreze was going to be used as something you spray on your towel before you get into it, so when you get out and your wet, the water will actually release those "bubbles" that trap dirt and release a good smell. Now, they've made it so it works for couches, sports, bags etc. but all it does is trap those odours for a bit (letting them just sit there) until you get it wet or sweat on it again re releasing those old odours plus the new ones.
Waste of time and money
