After someone posted about The Diva Cup a while ago, I decided to give it a try! Mainly because I wanted to try something silicone, it's cheaper, and it's Canadian! I am just at my first cycle now with the Diva Cup and I'm finding that it functions exactly the same as the keeper. The size of the Diva Cup is exactly the same as the keeper, although I think it's a little thinner. The Diva Cup is also harder than my keeper (but maybe because it's new?). My keeper was more pliable. I do like the fact that it's harder though because it expands a LOT faster in my vagina than my keeper did. Before, I use to have to wait a few minutes, turn the keeper 3 rotations, before it would expand. With the Diva Cup, the expansion happens right away. I like it. :) In fact, I think I like it more than the keeper!
