I purchased a set of these for a replacement for my Momcozy M1 pumps. MomCozy discontinued the individual parts and you have to buy a $60 each package (disappointed because I just bought it in Nov. 2022), it was hard to find the replacement. But then it was Lil' Nugget to the rescue!! 😀 I'm so thankful I found your company and had the order delivered the same day (to my extreme surprise)!!! I will be reordering from you guys going forward for all my part needs. If I ever need a new pump I will also be order from you. Thank you!
