I am using almost no detergent with this ball and getting clean clothes. I have not yet tried no detergent, but I imagine it wil be fine. This will save money as well as keeping more soap out of the water supply. I have ordered another one to keep on hand.
I was concerned about the price of this pillow, but am very glad I bought it. It is a good fluffiness without being too high so I bought another one for my child. I am glad to be able to use a wool pillow instead of synthetic as we spend many hours each night on it. I had bought a cheaper wool pillow from somewhere else and it smelled like the wool had not been washed. This pillow from Gaiam is clean!
