Pumping mill and gas at the same time. LOVE THIS PUMP! (The momcozy I mean, not the expensive gas haha) I seem to get a better result from it than my hospital pump (baby is in NICU so I'm exclusively pumping). Highly recommend!! Easy to clean and will only leak due to user error (aka not putting back together right oops!)
These are my favorite pumps! My medela barely gets 2oz. I have a medela and a lansinoh hand pump, they’re decent but not amazing. I also have an off brand set of wearables that get 2oz max. The momcozy s12 pros have gotten up to 4.5oz and it keeps slowly increasing! They’re super comfortable and the most efficient pumps I’ve tried! If you’re on the fence- it’s a must try! I’ve put more milkies back for my baby boy daily since getting these! ?
