Product review (4 stars): Bought as a stopgap, used it for over a year.
We got this because the washer quit right before the holidays and we wanted to wait and buy a replacement washing machiune when appliances went on sale.  Now that I have this, I will never buy another washing machine.  Love it.

- I recommend putting it up on a counter, workbench, etc.  Ours is on our head washing machine.  I think putting it down in the bathtub is awkward.

- I also recommend filling it with a hose instead of trying to hold the tub under a faucet.  I disconnected the water hoses to our dead washer and use those.

-- Some people dump the tub over because they don't like to wait for the Wonderwash to drain on its own.  I use the drain pipe and let it fall into the utility sink.  I think I will switch to a five-gallon bucket at some point and use the gray water outdoors for gardening or landscape plants.

-- The clothes look better than they did using the regular washer.  I think the compression pushes out the dinge by percolating out the old detergent from previous washes.

-- I bought a janitorial mop wringer and bucket to squeeze out the clothes.  I hang most of the wash on the basement clothesline and then do the rest in the dryer.  Some people buy a little electric spin dryer.

-- The tub holds about half of the normal load I use to put in.  It takes less time to do each load, though.  I can put both the top and bottom queen-size bedsheets in and then do the pillowcases with the towels.  If I was doing king size sheets, I'd just do the top and bottom sheets separately.  I do one or two tubfuls of laundry daily and our clothes hamper is usually empty for the first time in my life.

-- I timed out the spins and for a normal load, I spin the washing tub moderately slow 30 times in each direction.  If the clothes are very dirty I do double the number of spins.  To rinse, I can do more like 15 or 20 spins each way.

-- The stand has suction cups on the bottom but I put mine on an old bath towel as I splash a bit as I pull out wet clothes.

-- It was easy to assemble it.  Five minutes tops.

-- I use a fourth of the detergent I used to use, and much less water.  The dryer runs a bit longer as the towels and jeans don't spin dry but I hang most of my stuff on the line so I use the same amount of electricity to run the dryer or maybe a little less.

-- The shipping speed was fantastic.  I think I got it the day after I ordered it.

*** UPDATE: The Wonder Wash lasted over a year, with a lot of use. I literally used it every day. One day the glue quit on the axle peg which holds the tub to the supporting frame. I tried to repair it, but couldn't figure out a solution. I have now switched to a plastic laundry plunger.  I got my money's worth out of the Wonder Wash, and it got me started with doing my laundry without a machine. I am glad I bought it.
