My wife's mind boggles that so much money is spent on this stuff when you can buy a menstrual cup every year or two and face almost none of the cons: http://en.wikipedia.org/wiki/Menstrual_cup .. I wonder if this is one of those "the industry doesn't want this to happen" dealies. (Disclaimer: I do not have a vagina so don't have direct experience, but she raves about it.)
