Maymom Connector Valve Compatible with Medela Pump in Style MaxFlow, Freestyle Flex, Swing Maxi, Sonata, Freestyle Breastpumps Not Original Medela Pump Parts Replace PersonalFit Flex Connector

I have the Medela pump in style pro max flow and the connectors were awful, I got this to try and the first use I could tell an immediate difference in output and time spent pumping to empty. It also fits the parents choice bottles better than the regular Medela connector. I only took a star away because it does seem that very small amounts of milk will get in the diaphragm area, I’ve used it multiple times already and have consistently had the issue. Another problem was the silicone adapter for the tubing, in the picture the right tube is when the adapter is on as is and you can see that it’s too small for the tubing and it didn’t create a secure seal and caused bad suction; the left is after pushing the tubing all the way through the hole in the middle, it fit better and formed a better seal, the only issue then was it doesn’t connect fully to the connector, but it does still connect with no issues. I’m not sure if it would have this issue with the maymom tubing, but honestly it’s not enough of an issue to justify buying it to try. Overall it was definitely a great purchase and I will 100% buy again if needed!

The connectors work great. Giving 4 start because the little silicone tube size converters don't stay on and make it very frustrating to pump. But they offer a set that has a different type of tubing where you can eliminate this problem

Milk keeps getting sucked into the valve no matter how many different ways I try this. I want my money back but amazon says no, and that I have to work with the manufacturer. So I go to their website and try and create a “ticket” and it says that my session has expired when I try and click submit 😡
