Product review (5 stars): Works exactly as advertised
While it's not perfect, it doesn't claim to be either. Heavily soiled or stained items will still need to be washed in a machine. Clothes that dry after being washed with the Wonderwash could stand a fluff cycle in a dryer if you have one available so they aren't so stiff. They do come out cleaner though, and for small bits of laundry, like underwear, socks or polos, it works just fine and they do not take too long to dry.

I did not find any of the materials to be cheaply made whatsoever. Additionally, there are no assembly instructions and I found none to be necessary. Simply by looking at the parts, it is easy to see how they all fit together. I assembled the whole thing in about 5 minutes or less.

A tip that I've found, which I think a few others have posted as well, would be to let the clothes soak for a bit after you spin them around and before you rinse. The instructions say just to spin for a few minutes and you're done, but I had much more success getting out simple messes like pen marks when the clothes are soaked for 15-30 mins.
