The Bounce Dryer Bar is easy to use.  Just stick it to the inside wall of your dryer, and it does the rest of the work.  I have been pleasantly surprised at how soft and fresh my clothes have been.  I was skeptical at first, but it actually works better than the dryer sheets I have used in the past.  I have used it for about a month, and the clothes are still coming out just as soft and fresh as the first load I tried.  The only negative comment i can make is that it does look a little icky after awhile because lint begins to adhere to it.
