Review: 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.
Review: 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.
