Product review (4 stars): so I only use it to drain and will likely find a better quality replacement
This is an electric washing agitator with spinner, basically.  I bought this for my rv.  It does what I expected it to.  It is the smallest electric washer I have found.  You will need too ensure it is properly secured so is it does not "walk away"as it washes.  Ensure you have the top plastic piece secure in spinner or the machine will vibrate.  It is faster to fill with a bucket of water than the tubing that attaches to the sink.  The plastic tubing is cheap and flimsy, so I only use it to drain and will likely find a better quality replacement.  The directions do not tell you how much water to add and there is no fill line in the machine, so you are on your own.  The directions are quite crude so use common sense.  It washes well and the spinner really removes significant amounts of water to the point where clothes are simply clean and damp.  My kids call it a toy washer!  It does what I expect and works well for our RV and camping trips.
