Congratulations, such a great invention! I would be happy if teenage girls learned about this amazing product and see it as choice number 1 instead of cotton tampons. Information and knowledge spreads through the school system and some bloggers :)
According to me, there's only advantages to not have to use tampons and pads. I convice all my female friends to try a menstraul cup cause it's simply the best!
Best protection for one who works in white clothes all day, never had a single problem and soon my whole department will buy one (I work at a hospital) each!
