Review: Great Fit! - 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.
Review: Perfect inserts for the standard flange size. - I really loved how this works for the medela hand pump, since the standard is 26mm. I needed a flange that was smaller to get optimal suction for milk supply without damaging my nipple. Slides right in, and easy to clean!

I really loved how this works for the medela hand pump, since the standard is 26mm. I needed a flange that was smaller to get optimal suction for milk supply without damaging my nipple. Slides right in, and easy to clean!

### ⭐⭐⭐⭐⭐ Good product
*by M***K on February 28, 2024*

Currently I’m using these with my Medela handsfree collection cups since they are only made with a 24mm and 21mm flange. Slides right in, stays in place, easy removal for cleaning. Does not get milk trapped. Has help up to sterilization. Overall good product.
