Product review (4 stars): Not too bad.
Wonderwash will not beat a traditional washer by any means but it will get your clothes pretty clean. If you have sensitive skin I would suggest switching to a detergent you are not allergic to, other wise you will have to do several "rinse" cycles to get all the soap out. Also be aware that things like lint/hair can also clog the small drain and requires occasional cleaning. Purchase a faucet attachment with a rubber hose to help fill the tank, I find that hot water helps clean much better then cold. You may want to try pre-soaking your clothes with the detergent and using the Wonderwash to rinse them out, this will cut down on the number of cycles you have to perform on one load.
