Product review (2 stars): No Better Than Hand-Washing
The Wonderwash is clunky and awkward to use, and moves around a lot when you turn the handle. It's also pretty small, and *barely* holds a "full" load of laundry, which the instructions say is 5 pounds. The instructions also say that a full load of laundry only needs 1 gallons of water, but that gets *completely* absorbed by the laundry. In order to get a good "slosh", you need to add at least 4 gallons of water. And even then, it's really hard to imagine that those clothes are getting clean, packed in a tight drum with a little soapy water, and tumbling for just a few minutes. Plus, the laundry, the water, and the dead weight of the drum weigh about 40 pounds, which is *not* easy to turn with a rickety handle, while bent over the bathtub, with the whole contraption sliding all over the place.

So after trying out the Wonderwash and being disappointed, I decided to go back to hand-washing my laundry in a clean tub or sink, and that's actually a lot easier than fussing around with the Wonderwash. There are no complicated instructions to decipher, and no liquids to precisely measure. And I know my clothes are getting clean, since I wash everything one at a time, and I use a lot more water (so everything is floating around freely). I've been hand-washing in a tub for the past two months, and I'm happy with it. By comparison, the Wonderwash didn't save me any time when washing my clothes, and was actually a big hassle, and probably wasn't getting my clothes clean, anyway. But I suppose if you only put a few articles of clothing in the Wonderwash at a time, it might get them clean, I just don't see how that would be any easier or more efficient than washing them in a tub or sink.
