So I tried the meluna medium, classic, ball stem. It's a lot shorter than the diva obviously but something about the material makes this cup totally useless for me. I have no problem with the length and I have no trouble popping it open... The material is not really "softer," but it's more malleable and doesn't keep its shape. It's way more comfortable than the diva but it leaks because of the weak seal (or lack of seal). It's like, half in the cup, half of it comes out around the sides. Very disappointing because it's super comfortable!
So, what brand should I try? I was thinking maybe lunette? Sckoon?
