Review: Easy to clean and well packaged. - These 17mm flanges have been great! One of my favorite things about them is how versatile they are—I can use them with multiple pumps, including my Momcozy and Medela, which is super convenient. They arrived well packaged and are exactly as described. They’re also easy to clean, which is a huge plus when pumping multiple times a day. The fit works well and they feel comfortable to use. Overall, these are a solid option if you’re looking for compatible, easy-to-maintain flanges. I’m very happy with them and would recommend!

### ⭐⭐⭐⭐⭐ Works well
*by T***R on December 11, 2025*

They help me pump using my Spectra

### ⭐⭐⭐⭐⭐ Works for resizing Spectra flanges!
*by L***E on April 2, 2024*

I bought these because my Spectra S1 didn't come with my size (21) and I didn't want to buy all new flanges. These worked wonderfully. They are super inexpensive, fit well into all my flanges (including 22s for handsfree flanges I bought on Amazon before I realized my size), easy to place and stay put during pumping, quality soft rubbery material that reduces friction discomfort from the plastic flanges, and very easy to wash. I would recommend buying these if you want to resize your flanges without dishing out more money for new ones. Hope this helps!
