Product review (5 stars): Does What It Says On the Tin...
Maybe my title should rather be "Does what it says on the cardboard box / eBay ad".  ;)

I've worked from home for almost five years now and share a floor of a large house with a roommate.  For us, this thing is perfect.  It may not be as nice or have as large a capacity as the Haier 21N(?) portable washer that had broken down on us, but it does just what it is sold to do and we certainly have no complaints.  ^_^

As far as the capacity goes, i tend to do two or three medium-ish towels for one load or maybe a load of "one pair of jean" as the ad puts it, right along with a pair or two of thick, wooly socks.  Other than not overloading it, I've found the worst thing one could do is use too much detergent as it'll take many, many rinse cycles to get it all back out of the clothes.  (I just eyeball it myself, hence the mistake i guess.)

One thing of particular note:  When i first un-boxed the washer i had a real time of trying to figure out where to put it -- i was really perplexed, lol -- even going so far as to build a quick little stand for it where we had been using our previous portable clothes washer so it'd be near to a drain but eventually i realized the absolute best place was in one of the two tubs in our kitchen's stainless steel sink(s).  Fortunately the sink seems sturdy and well-built.  This thing rattles around a bit and when i run it on a real quiet afternoon it almost feels like it's shaking the house a little.  So i never really run it past 9 or 10pm, myself.

Oh, and i bought mine off of eBay, not Amazon.  Truth be told, i paid almost exactly the same -- so i should've done it through Amazon 'cause then i'd have been tempted to throw in some items from my Wish List along with the washer.  ;-)
