Can’t keep the duck valve to stay on! Worked okay for a couple weeks and then it continued to fall off a couple minutes into every pump

Read the description, because we bought it thinking we were getting 4 pcs and instead got 3 and when I read the description it said it was 3 pieces.

Works perfect on my spectra pump. The pink gives me a little extra motivation to make pumping fun.

It does not have enough suction capacity

After the original duckbill valve tore, I found these replacements were half the price of the original parts so I decided to try them. You can tell the material is thicker and a little different than the original manufacturer's parts, but it does work as intended. They have outlasted the original part so far (by about a month) and have not started to show any wear. I would buy them again.

I have now exclusively pumped for two children and these are above and beyond the best duckbills that I have used. I will only buy these when I need to replace mine because they give me the best suction and have increased my milk production as a result

Easy to use. Easy to clean. Can sometimes be challenging to get into pumps correctly.

In the picture and the heading it says it's 4 pieces but in the description it says 3 pieces. That's quite a sneaky thing to do honestly. I will not be returning it however because I actually need the product but beware!

I was so nervous to order these. From the photo I had no idea how it would fit on my momcozy. I ordered them anyways because the momcozy size I had was way too big and hardly got any milk.Getting the right size flange is a HUGE deal in pumping and helping you produce more milk. (Be sure to get measured at the hospital after baby and they'll help you get the right size!)But this product came in and is great quality. It was easy to assemble to my momcozy and was seamless (you can hardly notice I added them to the inside). They were the correct size for what I needed and helped create a stronger suction! The only downfall is it's one more thing to take off and remove but soooo worth it for having the right size flange.

I’m a breastfeeding/pumping momma who purchased a Momcozy pump and has a bit of elastic nipples. The size 24 flange I think runs a little big and it has a short “tunnel” so my nipple was getting pulled back far and getting pinched in the top while causing pain and loosing suction. I tried a Maymom insert and cut it to fit bit no luck. I tried the beaugen which worked a but was annoying. Sticky, never really adjusted to the correct size (always loose) and turned an ugly yellow color. I tried these and was worried they wouldn’t work because it covers the suction hole. But they worked! It covers the suction while but there is still room between the suction and the insert so it doesn’t effect output. I was so happy they worked I cried! This is the only insert that worked for me and my Momcozy pump. Saved my pumping journey especially now that I EP. In another review I saw that their insert stuck out a bit but mine goes all the way in. The first two weeks it’s snug and you have to gently push it in or even fold it a bit and flatten it out in the Momcozy pump. Over time it “molds” and slides in perfectly.
