I've been using my Keeper for a year and a half. I started having periods of Old Testament proportions due to peri-menopausal weirdness and I ordered my Keeper on the day I went through 17 tampons in an afternoon. The first month using the Keeper was one big trial and I had a couple messes, but after I figured out how to make it work/fit with my body it worked like a charm and I will never go back to a disposable product. I fold mine just like Dianyla does and get the edges wet to ease insertion. I've worn it on several rides of 50+ miles and never had it leak. It is so worth the investment in terms of money and in terms of the health of your lady-bits!
