Product review (4 stars): This is about as good as it gets for off the grid or just cheapo living.
My husband and I are living in an RV while building our dream straw bale home and the laundromat is miles away. This sweet non-electric washer, along with a spin dryer, is a godsend!  In an hour I can do three good sized loads, hang them behind the RV and an hour later (Arizona dry air) I'm folding the clothes and putting them away. This little gem will save me a ton of money, time and possible grief (from using public washers/dryers).
I don't like the fact that it leaks a little bit at the drain connection when putting the drain pipe in but it isn't a lot of water, and it is only water. Not that big a deal. On the plus side, I can wash EVERYTHING, including sheets - one at a time.  It holds a lot of clothes for how small it is. It is very light weight and I easily store it in the RV "basement" storage along with the spin dryer. I'm so thrilled with this washer, I tell everyone about it.  Why not 5 stars?  Nothing's perfect.
