desertcart.com : 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 : Baby

Review: Works as it should. Could use 1 small improvement - 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
Review: Horrible design - Milk keeps getting sucked into the valve no matter how many different ways I try this. I want my money back but desertcart 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 😡

## Questions & Answers

**Q: Which replacement duckbill valves will fit these? Looking for inside-the-hole type.**
A: I am hoping maymom will answer this question. I am looking for the exact same ones that ship with the product but everything I have bought from maymom goes over and not inside. They obviously produce them as they ship it with the product. The only ones I have found that go inside are https://www.amazon.com/gp/product/B00U30GSR6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 which are pricey

**Q: Where can I get replacement duckbills exactly like the one that come w/ this (Maymom Connector Valve Compatible with Medela Pump in Style MaxFlow...)?**
A: I bought the duckbill valves from their store. They have valves for several brands. I bought the pink spectra ones and they worked for my medela hand pump ( Maymom 6 Count Duckbill Valves... https://www.amazon.com/dp/B0834W5CKQ?ref=ppx_pop_mob_ap_share ). Didn’t have to replace the valves on these before I was finished pumping, but I would think they would work just fine.
