I have seen the bounce dryer bars for sale at a few stores, and thought that the price was really high, and it was insane to put something inside your dryer. I used the bounce dryer bar, and was pleasantly surprise! It made all my clothes smell awesome, and it was gentle enough that it didn't upset my allergies! It was very easy to install, and I am still using the same bar now, 1 month later, with plenty left! I am hooked!
