I found one of these on ebay today and it was $20 shipped to me, so I figured why not? I currently use an older style large Yuuki. Since Yuuki changed their cup a bit (I posted about that a day ago) and need a larger capacity cup due to my heavy flow, and I need a long cup due to my incredibly high cervix (sometimes I can barely reach the stem on my Yuuki), I decided to give this NaturalMamma a try. Once I get it I will do a comparison to my Yuuki. Has anyone else tried this cup out yet?
