Pros: Softens clothes naturally while not needing chemically treated dryer sheets
At first, I bought two of these little, prickly blue balls to see how they would perform. My clothes seemed just as soft as before...however, I missed the "fresh" scent that I was accustomed to from the dryer sheets (even though I knew it was bad for me and the environment). After only a few uses of the balls, the missing scent was barely even a faint memory and I was sold on the effectiveness of the blue, prickly balls. A week or two later, I bought 2 more balls and now use all 4 of them at the same time. The manufacturer suggests that 4 balls speed the drying time even more so than 2. I don't know if this claim is true, but it makes sense to me. I love my 4 blue, prickly dryer balls and would never go back to using dryer sheets!
