Product review (5 stars): cleanest clothes ever! SEE ADDENDUM AFTER 1 YEAR OF USE...
Stains are fading! I've been using it for approximately 1 month now and I've noticed the stains in my dish cloths and cloth napkins are fading away! My clothes seemed to be looking better but I thought it was my imagination, until I noticed & watched those specific stains. I guess it's the smaller loads or something? Whatever! It works better than the standard washer I was using... And it's Eco-friendly! Win-win!
  If you were wondering about ease of use... Be sure to measure the water, per the instructions, and away you go. I do switch arms to keep the workout balanced... Generally, 2-3 loads each day I do laundry; alternating arms by day, not load. Once you get it going it's 100% aerobic...but EASY! The water gets flowing & it is almost self-propelled; if you feel like you are struggling you have too much water or clothing... Or you didn't get it going fast enough, crank faster. Once you get the speed right, the water seems to do most of the work. Just remember not to smash the clothes in too tight and you should be fine. [When you drain the water, if the clothes fill more than half of the washer... you got too many clothes in there!]
  As for drying, I use the Nina Spin Dryer - also from The Laundry Alternative. They are a perfect match. By the time I finish another load in the Wonder Washer, letting it drain for a while between "cycles", the prior load is almost done hang drying. I let the rinse drain until the first load dries, then I spin dry and hang. It makes the process almost relaxing. A friend stopped by while I was washing & was amazed that things hang dry as fast as his big electric dryer can dry things. He was also amazed at how much fit inside the washer...looks can deceive.

ADDENDUM:
  Now that I have used the washer for a year, let me just say that my clothes like the gentle treatment! Stains don't last, fabrics have smoothed out, and the things I have purchased since buying it still look like new... it's like a front-load washer only MORE gentle!
  I see that they have updated the lid, which I think is a great idea. The first time my daughter used mine she didn't get it closed all the way cuz my old style lid requires many turns to tighten/seal it... she spilled water everywhere. But just once!
  I have oiled it once but it is squeaking here & there so I will probably have to oil it again soon... making oiling necessary about twice a year. I haven't had to replace any parts but they are all available from The Laundry Alternative. It was super easy to put together [when it arrived] and replacing parts that break instead of buying an entire washer is another bonus.
  I have to admit, I do 3 cycles most of the time.  I do the detergent cycle, a white vinegar cycle, and end with a softener cycle. I crank each cycle for the 2 minutes they recommend for washing. I count 120 cranks; as the cranks take about 1 second each. That's 6 minutes of cranking per load. [Super dirty stuff gets extra rinse water thrown in WHILE DRAINING & comes out clean.] I also alternate forward & backward cranking, not just left & right arms, & my arms look GREAT! Just thought I would throw that in.
  I should add that I am enjoying the exercise factor. It has gotten so easy to crank that I love doing laundry! I also find that the rest of my body benefits from the isometric exercise; holding the rest of my body still while cranking has toned me from head to toe...And my clothes look great on my toned self; more bonuses!!!
  One year later, still cranking & loving it!!! ^_^
