The Mooncup I purchased was the U.S. version. It didn't really work out for me either. I experienced major cramping with it in even though I couldn't really feel it in. I tried all the various ways of placing it that I found online but the cramping persisted. And if I found a placement where the cramping went away, it leaked to the point that I may as well not be using it at all. Oh, well... Back to tampons for me.
