Momcozy 1 Pack (Full Set-24mm) Replacement Accessories for Upgraded Mobile Flow

As a whole, I would not recommend this pump. The flanges break easily. I have been using this pump a couple of times a day, 5 days/week for a month and have had 3 flanges break. The prongs that connect the flange to the valve/collection cup are what breaks off, rendering that flange useless due to a complete loss of suction. The pumps themselves, once assembled with the flange and cup, are bulky and don't stay in place well. I had to purchase a support band to hold them in place for it to truly be hands free. The collection cups are difficult to wash and get all of the milk out of, especially if it separates or sticks to the sides after being in the refrigerator. I would not choose this pump again.

Terrible pump design. Too many parts to clean. And the milk collection cups are hard to pour. I bought this replacement part because the clip part broke and this one broke the same. It's hard to snap on and off. You are better off buying a different pump

Would give less than 1 star if we could - pump is alright, but get ready for the flange to break all the time and then render the pump useless. The clips on the flange are brittle and plastic - they will break after 10 days or less of use … good luck

I wanted to love Momcozy and was so excited to get my M9 pump. I went ahead and ordered a second set of parts so I didn't have to wash as much. The seal on these are complete garbage since they changed the valves. There is no 3rd party you can buy from either. For $100, you would think the quality would be there, but its not. I can't even use my M9 pump! My supply has also suffered because even the new replacement parts don't have a proper seal. I highly recommend not wasting your money or Amazon's money whenever you have to return these unusable parts. I started out getting 5 oz with the OG parts, and these only gave me 2 oz. I lost so much milk and am so upset about this! I have a useless $270 pump, because I can't find proper parts that work like the originals. I will update if Momcozy fixes this, but otherwise, please save yourself some time, money, and milk!

Not worth buying this pump or its replacements parts as it is poorly made and breaks often regardless of how careful you are with it.

Parts don't fit together to create a tight seal, will lower milk supply over time. Bought these replacement parts as I exclusively pump, and noticed a decrease in my milk supply after a couple weeks of using them. When taking the pump apart, I noticed that the "new upgraded duckbill pieces" don't fit into the flange and there is a gap between them. Luckily I was able to find my "old" plastic duckbill pieces and found replacements for those as they work much better.

Flange keeps breaking. It lasts around 5 pumps

White piece on duck bill keeps snapping off when clip on the milk reservoir. Super irritating when it’s your only pump besides a manual. Customer service was good though.
