Product review (3 stars): Not for those who have been spoiled by the use of an automatic machine
I bought this product as part of an initiative to use gray water from the bath water to wash my clothes.
Wonder wash  is easy to set up and sturdy enough. My plan was to do three loads of laundry white medium colored and dark using one washerful of water and soap and then rinse in the same way. I followed the directions adding more soap than was called for. I doubled the time for spinning the tub to ensure proper mixing. 3 rinses were necessary to rinse properly. The clothes were not cleaned to my satisfaction. I found a place in my closet for it and have not used it since
It is sad that automatic washing machines cannot use (clean) gray water from a bath.
