Product review (4 stars): Paid for itself in 2 months.
I have been using the Wonder Washer for several months.  Before I was going to the laundry-mat every week and spending about $10 each week.  Now I only go once every 4 to 6 weeks to wash the larger items.  This machine paid for itself in about 2 months.  The loads are small, only 2 blouses at a time (maybe 3 if they are very light weight).  I tried washing 3 medium weight blouses and the machine started moving all over the counter and was having trouble swirling the clothes.  The knobs are hard to turn (only about 1.5 inches in diameter) and lifting the wash-tub (the manufacture calls it a bucket) on & off the base-unit takes some doing as it is heavy when full of water (total weight approximately that of a 3 gallons bottle of water).  The machine washes by spinning the clothes one directions for a few seconds and then the other direction a few seconds back and forth for the duration of time you selected.  A little like the front-load washers, only this machine spins the clothes clock-wise and counter-clock-wise.  It only washes, you must raise the soap out by hand as well as ring-out the wet clothes and hang to dry.  The size of the machine is about 20 inches tall and 14 inches across.  If I could suggest improvements they would be: 1. Larger knobs with deeper indentations making them easier to turn,  2. A drainage spout on the side so that after washing the water could drain out into the sink.  Lifting the wash-tub full of water and wet clothes of the base-unit and turning the whole thing upside-down to grain the water out is the thing I like the least.  Overall, I am happy with my purchase.  It gets my clothes clean and it saves me time & money.  This was a good investment!
