Product review (4 stars): Great product, poor documentation
I purchased this washer a little more than a year ago, and once I got the bottom plate on correctly (which is not easy to tell from the documentation), it's been great. Several others have mentioned this, but you want to put the metal plate thing on so it bulges out, rather than in. If you put it on bulging in, you will hear TERRIBLE noises when you try to do laundry.  With it in the right position, it is actually quite quiet.

I've had a few spills, but not due to anything the washer did--my sink was actually clogged or partially clogged and overflowed.  This was not the fault of the washer in the slightest. I've never had any overfilling issues with the water on the high setting, and as long as I don't overload it, I don't have a lot of unbalancing issues.

Keep in mind that a pair of jeans is 2-3 lbs, a t-shirt is about 1 lb and that the capacity is only 6.6 lbs and you shouldn't have many problems with overbalancing. :)
