I think the rim is kinda like the small Divacup's rim...pretty much the same size around that area. The other cups still hold more fluid. I really like the stem on it because it's flexible and flat, I don't have to cut it off. It's really soft. It's smooth and doesn't have big indents(or ridges...don't know the word)like the other cups which I can sometimes feel when I remove them.

I really like it. I didn't use it a lot but for me it's more comfortable to wear and remove(I don't remember insertion or how easy it opened). It's short kind of like the Mooncup UK but not as big around the rim. There's 4 suction holes in it that are bigger and in a different position than the other cup's holes. And the cup is still shaped a bit differently. Anyway...I think why I like the cup has more to do with my vagina shape. Every cup is a good product and probably compares differently to different people.

thanks for the info..

The capacity is 20ml (as much as in smaller Diva), bigger Lunette's capacity is 26ml.

Thanks...Wow...are you sure that's right, given that its the same diameter as the Diva, but 1 cm shorter?

No, I'm not sure, because I haven't measured it by myself, I copyed those numbers from one Finnish menstrual cup infosite :D. I think it's about where the small vents are. If in the Lunette they are upper, it's capable to keep more blood than Diva.

Ahh...that's cool. Thanks for the info. Looks like this might be something to try for me in the near future. :)
