i actually saw this and thought about getting one a few months ago. i'm also curious to know if anyone has tried it out!
I used to have one... It works well but you have to touchy icky diapers, lol. I highly recommend getting the spin dryer (sold separately at the same place). When I used it, I was using flats so I can't comment on how it works for anything else. Be sure to wring them (by hand) or use the spin dryer after every washing... Basically do your cold or warm 'rinse' and then take them out and wring them, do you hot wash, wring them, warm/cold rinse, wring them, etc. Overall it worked well for my flats but it is time consuming!
