The Bounce Dryer Bar is a great idea.  You put it in the dryer and forget about adding fabric softener to the wash or dryer sheets to the dryer.  I don't know yet how long it will last, but it does a very good job softening my loads.  Personally, I perfer less scent in products.  This is heavily scented, perhaps because it's so concentrated.  If you like your wash to have a sweet smell after drying, you will definitely like this product.
