I bought the large ones some time back, but when they arrived one of the seals was defective. The pink thing had come out. I just pulled the pink part of the seal out of the other cup and attached them to my noogleberry hand pump. I have to say they're so much lighter and more comfortable than the cups that came with the NB!! Also the silicone rim gives a better seal. The large NB contoured cups hurt my ribs so badly that I couldn't pump enough. I LOVE these cups!
