## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Fit!
*by A***Y on September 19, 2025*

I love these inserts! I use them with my Eufy S1 Pro and they fit great with it. I have also used them with my Spectra but they are a little harder to fit. I actually like them more than the flanges that came with my pump.

### ⭐⭐⭐⭐⭐ Work great in spectra flanges
*by R***O on November 17, 2024*

These inserts work great in my 24mm Spectra flanges! They are easy to insert and remove, and they are easy to clean! I will definitely repurchase!

### ⭐⭐⭐⭐⭐ Great product
