Product review (4 stars): Good at what it does, but not miraculous
I use my wonderwash about four times a week, mostly for small items like cloth diapers (pre-rinsed by hand first), baby clothes, socks and underwear.

For me, it does what I wanted it to do, which is save the vast amounts of money we were previously spending using the $4 washers and dryers in our apartment building. I'm glad I got it and would buy it again.

The pros:
* Clothes really do come out clean. Even diapers. No problems.
* It doesn't take too long. Not as super-speedy as you might expect given that washing takes only two minutes of handle-turning and rinsing takes one minute, but still, it's about 10 minutes a load even with the poor water pressure in our taps. (The time-consuming part, for me, is filling up the washer with 6 quarts of water, once for washing and once for drying, and also waiting for the water to drain out again after each part of the cycle.) I used it in the bathtub once, where we have much better water pressure. The filling took only a few seconds, but the turning was much more awkward. So now I do it on the kitchen countertop and drain into the kitchen sink.)

The cons:
* It's not horrible to turn, but it's not just a quick twiddling of your fingers either. There is a moderate amount of actual effort involved.
* DON'T FORGET THAT THINGS WILL COME OUT SOPPING WET. The machine doesn't spin at all, so you have to get the water out yourself by wringing things manually. This takes a while, especially if your load consists of a billion small items, and all the wringing is more effort than turning the machine. If you did this to a no-iron shirt, you'd get horrible wrinkles that would be tough to get out even with an iron. And also, no matter how well I wring the clothes, they still end up considerably wetter than they would be if they'd been through a regular washing machine with a spin cycle. Since I hang clothes to dry in our apartment, that means I wait about 12 hours for them to be completely dry, rather than about four. This means that our apartment is almost never free from "decorations" of socks draped over the chairs. I think it is probably worth getting one of those mini-spinners too, to take care of this problem.

Tips:
* As I saw in someone else's review before I bought it, it really is easier to turn the handle if you have the full six quarts of water in it, even if you're not washing a "full" load of clothes.
* Don't use much detergent, or you'll have to do more than one rinse to get rid of it all. The clothes really do come out clean even with only a teaspoon or so. Less if it's the HE stuff.
