I just got my Instead cups a few minutes ago, and though I don't have my period, curiosity got the best of me. So I opened up the box and then took one out to see what it felt like. It reminds me a bit of a female condom, but with less material, firmer rubber, only one ring and they're worn the reverse way to catch fluid from within the body. I can't speak for leakage yet, but if the similarities continue with comfort level etc once I insert one, I'll be all set to go. I only wish these things weren't disposable. I'm very happy for the time being, but we'll see once it comes time to try one. I probably should do a dry run, but since I only got six, I don't want to waste one.
