I bought this product after much research, because I have a detergent allergy. Despite consistently positive reviews I was very skeptical. However, after much back and forth I think me but then decided to appoint the nuts. And I must say, I was convinced. I can only confirm the positive reviews. Even the absolute hardness test: my riding clothes that no longer even partially totally untainted by normal detergents. This I have washed with soap nuts in the third round and I was completely floored when all the stuff were cleaner than when I washed it with detergent. Round: I am now Waschnussfan and have these already some acquaintances recommended.
