I was very excited to buy some wool dryer balls yesterday. I tried them out today and sadly I found that they did not reduce my drying time nor did they make my diapers less stiff. Defeating the 2 main reasons we bought them. I contacted the store I bought them from and they will not return them and suggested that I give them more time. If they didn't work the first try, can anything be gained by sticking with them. Is there a "breaking in" period and maybe they will work better over time? Or did I just get some lame balls and now I am stuck with not being able to return them?
