Product review (2 stars): Do better wonderwash.
Not thrilled with this product. Got it thinking it would make manual laundry at least a little easier. Somehow, I'm still hand washing and handwringing my clothes. The plastic on this appliance is flimsy and wobbles when cranked. Takes two people: one to crank and the other to hold it in place since the 4 suction cups on the bottom do not work. It leaks too... so kinda messy.
You can only really fit a couple things at a time since you don't wanna overload it.  And nothing too big!
At this point I've decided to just stomp around on my laundry in bathtub. That way I can do more than 5 articles at a time.
The best part about it is the water release feature at the bottom. It's a cool concept but needs to be developed. I want to be able to do my laundry sustainably and efficiently, but this is just not worth. Do better wonderwash.
