I was so thankful to stumble upon this enthusiastic and informative group of cup users. I only recently discovered cups (where were you 20 years ago?) and this forum has provided so much information. I tried a Keeper from my local health food store, but experienced leaks and had a difficult time with removal. From the posts here, I decided to try the Lunette Selene. I will never willingly go back to anything else. I love my Lunette. Thanks for sharing your experiences.
