Product review (3 stars): Not the greatest....
I bought the Wonder Washer and also the Spinner.  I used it on the kit counter, not in a bathtub as my back could not stand the bending over. I even bought a short hose and hooked it up to the kit faucet.  It works great for small things, not for jeans, sheets, coats, etc.  Going from the washer to the spinner requires squeezing the water out as you pull the items out and can get a bit messy on the transfer to spinner.  If you don't have a spinner, then you will need a place to hang the items while they DRIP dry.  You need to rinse at least twice. I found the unit very time consuming. Also, the handle broke after awhile from all the cranking back and forth, had to replace it.
