I have a small Mooncup USA arriving any day now and I will post some pics and give my experience with the mooncup!
EDIT: About the fleurcup stiffness, I think I found the problem. Although the fleurcup is easier to squish, it springs back MUCH more forcefully than my divacup, leading to my "rating" as a 6 and the diva a 4. After close inspection I think I figured out why. The silicone on the fleurcup is stiffer, but is thinner than the diva. This explains why it compresses easier but springs back stronger. The silicone is softer on the divacup but is thicker. It is harder to compress, but doesn't return its shape as quickly. Anyone else have both a divacup and fleurcup that can try to confirm/ disprove my theory?
