Product review (2 stars): Worked unti it broke... two weeks later.
Living in New York, I saw the Wonderwash as an amazing chance to opt out of the laundromat.  I bought the Wonderwash after seeing several similar products online.  I was pleased by the results I was getting in terms of cleanliness and ease of use... but two weeks in the handle snapped off.  For some reason while the rest of the plastic was relatively heavy duty, the part which would be getting the brunt of the torque from spinning was made of soft, malleable plastic.  It squeaked for a bit, then just ripped off.  On the plus side, the vendor was great about returning my money!
