Product review (2 stars): Not worth it
I bought this thinking I could save money and energy.  Yes, the wonder washer does a good job of washing.  However, by the time I'm done rinsing the clothes out and then ringing them, I feel like I may as well have hand-washed the clothes.  The instructions on how much detergent to add are useless unless you know how much your clothes weigh in grams.  If you've done a lot of laundry in your life, this shouldn't be much of a problem, since you can just eyeball the correct amount.  The washer is not always very stable and does not lock into place very well.  Sometimes when I use it, the whole thing spins around.  Other times, water splashes out from under the lid, since that does not snap down.  I am also finding that when I tip the washer over to drain out the water through the lid, the lid bends under the pressure.  Again, this is probably because the lid is not completely held on by anything.  Overall, this product can take a little time out of hand-washing clothes, but you will do almost as much work.  It did not meet my expectations based on the reviews I read.  I would not find this product helpful as a college student or a mother, as it is more time-consuming than meets the eye.
