Organic Wool Dryer Balls (4pk)Product Rating: Product Review (submitted on July 29, 2013):
I was so excited to use these balls but was disappointed. I use all 4 dryer balls for cloth diapers as well as regular laundry and, I don't see a difference in drying time. I usually just run the dryer a second time to get the damp diapers/clothes completely dry.
I really wanted them to work, so sad.
A note from Parenting By Nature: Depending on the size of your machine, some individuals find they will need at least 8 for a noticeable difference. Four is a good starting point, and should help with softness, but for a dryer that you are generally running 2 cycles to complete, definitely add more balls to help with lofting and absorption. Good luck!
