Product review (4 stars): No-Hassle Backup Washer, and Spin Dryer Idea
I've had this model of mini washer for years as a backup, and while I rarely need to use it, when I do it's a godsend.  I've used it for items I forgot to put in the regular wash load but need ASAP, and for extra-soiled items like garden gloves and slipper socks.  Four stars is because after a few years the screws rusted and the machine got a bit leaky.  I've ordered a new one from Amazon as it's the best value for this type of machine, and perhaps the new one will have stainless steel screws (although I doubt it).  After rinsing and wringing out the clothes I let them line dry for a while before finishing them off in the dryer.  The Wonder Washer does the job simply and very well when used within its limits (it does not take large loads or spin dry the garments).
UPDATE:  I've discovered the perfect companion to the Wonder Washer:  the O'Cedar spin mop!  After washing the garments, you can give them an optional rinse in the O'Cedar bucket, then spin-dry them in the O'Cedar spinner.  It really gets a lot of water out, so you can put the garments right into the dryer without having to wring them out.
