Product review (4 stars): I just did a few loads with the Wonderwash and am satisfied with it
I am a student who lives in an apartment without washer/dryer and don't have a car to go to the laundromat. I just did a few loads with the Wonderwash and am satisfied with it. The assembly is easy, the size of the item is both sufficiently small to be used on a kitchen top yet big enough to wash a few days worth of laundry.

Make sure you put the Wonderwash on a wet surface so that the suction pad can maintain the item while spinning. Also, do not start cracking it too fast too soon, build up the speed gradually.

Personally, I put the detergent first, then fill the Wonderwash half with hot water, add the clothes and give a few spins to pre treat. After 5-10 mins, I start spinning continually for 10 mins. It is not hard to do, when the movement is started you barely feel the weight. Once again, make sure your suction pads will hold it in place. The cap does not leak and the tube provided to drain the water is very efficient.

So far, the only real con is that when you are done, the clothes are so wet, you have to hang them above a tub for a few hours before they are fully drained.

I'll keep this review updated.
