This specific model works for me, but only if I use them with the silicone rings. I have to get them angled just right, it took me a few days of frustrating practice. Now I can pop them on without looking. I can definitely see how they won't work for everyone, but for me personally they're really helping with the expansion of the sides and overall "roots" of my breasts. I chose the contoured version because I have a very small ribcage and was worried about the non-contoured version not fitting at the sides.
