Product review (4 stars): An Update - and Suggestions
Update - After rinsing in my sink, I realized I was probably washing as much as rinsing, so I've finally gone to just washing in the sink, rinsing and using the spin dryer.  I'm giving the WonderWash to the thrift store.  Works fine, but just isn't necessary.  The spin dryer, however, is!

I've been using this washer for a month and I'm very happy with it.  Does a great job of cleaning the clothes and is quick and easy to use.  Never realized that my ordinary clothes got so dirty. Here are some suggestions for making the process as easy as possible.

1) Sort the clothes into a few piles with the dirtiest done first, gardening clothes, for instance. Any leftover soil (very little) will be washed out with the next load.  One advantage is that you can fine tune your wash so anything that needs bleach, for example, can be done separately.

2) A pound of clothes is quite a bit, unless it's a heavy fabric item like jeans.  A scale to weigh loads is useful and I happened to have one already. I like to do small loads since there's less effort per load.

3) You can rinse in the Wonderwash, but I much prefer doing it in the sink since I can see the water and can refill several times more easily.  I have a double sink and I put the washer on one side and the mini spin dryer on the other.  Very easy to move everything from one to the other.

4) The mini spin dryer is a great addition and really does get out more water than a regular washer.  It doesn't take a full Wonderwash load, but it's so easy to use doing two is no problem.
