Your Review: Do wash balls work - Yes/No?

There is some controversy to wash balls. The claims of their effects are so bold that you can not help to doubt if these things really work or are they just a scam. Especially since they are often sold by different marketing pyramids and net marketing plans. These sound suspicious to me right away. On the other hand they are also sold by different eco and green shops who mostly take great pride in their product range and are careful about what they sell.

So, this is the post for your wash balls reviews. What do you think? Do you maybe use wash balls at home? How do you like the results?
