I see a lot of talk about the silicone cups that are out there, but I loved my keeper for nearly 12 years. The natural gum rubber/latex of the keeper finally dried out and started to smell so I recycled it. I already bought my new keeper and will use it for as long as it lasts. Oh and I thought I would mention that I have never had an issue with my 'cup' leaking. I have recommended the keeper to many friends and my wife, but none have them have started using it...yet. This is a great forum to discuss 'cup' issues.
Down with disposable tampons and pads! What a waste.
