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.

### ⭐⭐⭐⭐⭐ 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!
