to clean your laundry?!

... You get enough to do 200 loads.....No more detergent or softener needed...It's supposed to be "natural", no chemicals....I'm having a hard time believing these nuts can
remove dirt, by the looks of them they would create dirt....
By the end of the cycle it looks like I would have dirty clothes and clean nuts.....Bouncing nuts in the washer, what ill they think of next?.....Maybe it's the same concept of beating your clothes against a rock?......hhmmmm.......Has anyone attempted to used this?......
