I just got a lady cup (small) after using the small divacup for about 5 years. Holy crap, the lady cup is SO MUCH more comfortable! Whoa. The divacup was just too long for me, and I suspect either too large or too stiff, because it was always making me feel like I had to pee. Haven't had that problem with the ladycup so far, although I've only used it for a day.
Anyway, I'm super happy with the comfort aspect, but I'm having a heck of a time with removal! It is so slippery, and since the bottom doesn't have a little stiff part to grab on to, its really tough. Plus it seems to be suctioned so much more than the divacup. (I'm actually a little worried about my IUD for that reason, but we'll see how it goes.)
