Hi Kayye!
Thanks for the description! Not confusing at all either! I'm really having trouble with my nb. I took Matt B's advice and got some camper tape and put it on the cups. I'm having the same problem when I pump, I can't get the cups to seal up. They fart while I'm pumping, then as soon as I move my arms, they sound like a whoopee cushion. Its like something is wrong with my body why I can't get this nB to work. Everyone else, they get their's in the mail, they use it. I've been trying for several months now and I can't even get the cups to stay suctioned on. I had a Brava, which i had no trouble using, but the domes started getting really worn out and I needed money and sold it on ebay. I can't afford another brava right now. But I'm going to keep trying until I can get them to work. Keep up the good work!
