I've used the Diva Cup for several years and I recently tried the Lunette (see my review here). I've thoroughly compared both to help you choose which one is best for you. We carry both in our store, Cloth Diaper Outlet.
|Both comparison cups are Size 2.|
|Both come with pouches to store your cup when not in use.|
|The stem on the Diva (left) is a lot shorter than Lunette's, but the Lunette's actual cup is shorter by several millimeters. This could make a difference in comfort for women who have a low cervix or who have a short vagina.|
|Not my best photo, but you can see that the Lunette is shorter than Diva.|
|The rim on the Lunette (right) is a bit thicker and firmer, but the circumference of both cups is nearly identical.|
|You can see the circumference comparison best in this photo...nearly the same. Lunette might be a millimeter narrower on the outside.|
|Diva (top) has a softer rim, making it squish more under pressure. This makes folding it and holding it while inserting easier. Lunette (bottom) has a firmer rim. I find the firmer rim helps the cup to open better, so I think Lunette is easier to get into place.|
In short, Diva is a longer cup with a softer rim. It's easy to fold, but can be hard to pop open once in place (thus the "Diva dance" where women do squats or kegels to get the cup to open).
Lunette is a shorter cup with a firmer rim. The firmer rim makes it harder to hold it while folded, but once in, it pops open right away and slides into place.
For removal, I completely trim stems off of my cups so I have to grasp the pointed bottom of the cup. I think Diva is a little easier. The bottom of the Diva is softer, as well, so it's easier to firmly pinch the bottom of the cup and pull it out. The Lunette, being firmer, is harder to pinch but this is easily overcome with a little practice.
Overall, I like both cups. Neither leak during the day and seldom at night. Once in place, I can't feel either one at all. I recommend both, though I recommend Lunette for beginners because of how easy it opens.
