Nice hunt @calprut. Below are my personal comments towards your hunt.
Pros:

• a very nice product / machine to save energy
• not only energy, it will also save time, water and money
• portable
• easy to use
  Cons:
• none so far

I wouldn't say that using your own hand to cycle the machine is a con, doing so is actually a form of exercise. So while washing your clothes, you are also burning some of those fats. Nice right? :)
