I've been using a Lansinoh pump a friend gave me, her twins are now 6 years old and she used the pump for a year so that's how old it is. It works fine but I'm wondering if I'd get more yield if I buy a brand new pump. Anyone have experience with upgrading an old pump and getting a lot more per pumping session?

It was 10 years old and since I am an exclusive pumper, I wanted one that was brand new. She let multiple people borrow her pump. Not that I know if it was better or not to buy a new one but I just felt it was a better choice personally.
