Fit my M5’s perfectly
I bought these because I was concerned I was having less output using my Momcozy M5’s with a longer flange. These fit my M5’s perfectly, are easy to get in and out of the pump flange, and provide good output. They’re very comfortable to use. Definitely would purchase again, especially for such a good price.

Better than the originals!
These replacement parts fit my momcozy m5 perfectly! I was a little skeptical because most duckbills are loose but these are better than the ones they send with the pumps. Will repurchase again once these are worn.

It’s a little hard to take off, but works!!!
I was so worried about ordering these and hoped they would fit my Momcozy pump. Luckily they snap right on and work just as good as the original parts. However, they are difficult to take off of motor. I don’t know how to explain it. I almost took off a star but since it still works well and saved me money, I decided not to. It’s just a little frustrating when it’s time to remove them from the motor. But I would definitely still recommend them instead of paying nearly triple buying the actual replacement from Momcozy.

Better output!
Works very well with mom cozy pump and goes together tighter. Finding I’m getting more output from these cups than I was with original set. Also cheaper to buy individual than any “set”. Helps with EP and having a backup to not wash immediately

Fits Perfectly - Be Careful with Washing
Having extra collector cups is such a lifesaver while pumping and these are perfectly interchangeable with the momcozy ones. Be careful how you clean them though, I microwave steam them when I'm in a pinch, and I learned that after a while, it messes up the flanges.

Doesn’t actually fit M5 - don’t buy!
This did not fit the M5 pump when compared to actual momcozy products. There is a few millimeters of “give” between the pump and the cup where it doesn’t get fully suctioned resulting in not as much milk. At first it was only evident on one of the two attachments but unfortunately after one use it was present on both. Hopefully you can see in the video that the pump isn’t fully seated on the second attachment as compared to momcozy on the first attachment. Save your money - don’t get this!

Hard to remove from pump.
Sturdy against the use of time but can be a challenge to remove from the pump. Not for those with dexterity and or finger grip issues. The pull tab is more of a pain.
