You know I'm a pro at milk production, but I've never used an electric pump. I get the thing working right away. It's making sounds. It's squeezing my long, dark nipples. But, I don't see any milk being deposited! I stop and put everything together a little tighter. Now it's working! This machine is loud and pressurized. While I'm trying to find the sweet spot, I know I'm making more than enough milk to fill this container. My hardening breast begins to leak waiting for the machine. Now that I've got it figured out, I'll knock out tons of milk next time. I just had to share my first try with you all anyway!
