I use an Ameda purely yours. It's a year old but hasn't been used until my little one. All the parts are new. The motor part seems to work fine. I believe it fits right.
My lil one is 3 months. I had been pumping at work since 8 weeks. But just this last week y supervisor decided she didn't want me to pump. So now I can only pump at lunch and after 3.
I was producing fine until this. I look at pictures if him in my office when I pump.
