Whew this thing reeks right out of the box!  No wonder it lasts so long.  I suppose they had to inject so much odor to be able to make it last.  Seems like an easy item to use since it just sticks inside the dryer.  The downside is that I don't use fabric softener for every load.  It makes towels lose their absorbency so I'd have to be able to remove the sticker.  And I wonder if the sticky backing leaves residue inside the dryer and I can imagine seeing socks and other such garmets stuck to the dryer's insides.
