Product review (5 stars): Very happy 2 years later
I bought this washer 2 years ago, to help alleviate our growing laundry once we had a baby.  We live in a 3rd floor apartment with one coin-operated machine in the basement, and we now have 2 kids.  We use this in combination with the Spin Dryer Portable Clothes Dryer, and it is so useful for all handwash items & any lightly soiled regular wash.

It takes about 3 loads in the Wonderwash to equal one standard load, and when using with the Spin cycle it takes me about an hour from set up to clean up.  It doesn't clean things very well that have sat in the laundry basket for a long time, nor is it great for stains, unless you pretreat them and wash soon after.  The clothes definitely come out clean and as long as you don't overdo it on the soap, it really is a quick wash (as little as 1.5min for light loads!) and the rinse is only 30sec. . .it's great.  About the soap, I overdid it once & I wasted so much water having to rinse it all out that it's almost embarrassing to tell. .  .

After 2 years it's still in perfect working order.  No parts show anything more than minimal wear.  The only thing is the little white ovals that were meant to cover the holes in the frame where it connects together fell out early on, but they were only for cosmetic reasons anyways, & well, I don't see that aesthetics matter much for this little guy.

PROS
washes & rinses FAST!  1.5m-5m wash, 30sec - 1m rinse
perfect for delicates, great for lightly soiled clothes
Use less soap & water than a full size washer
Stands up to wear & tear

CONS
a little tipsy if you add clothes before the water, but you are supposed to add water & soap first so I guess that's just MY problem. (I wish all the time i could just toss the clothes in as they get dirty, then once full just add the water & soap)
The suction cups on the bottom are a little annoying if you need to move it often, since you still have to hold it steady with your other hand while you spin.  I'd prefer just a grippy texture on the base, but I guess that's just personal preference.

Summary - well made, nice little product for a more economical, environmentally friendly washer.  It handles almost anything, and works as well as the amount of effort you are willing to put forth.  I am still very happy with my purchase 2 years later.
